>> strangers in a strange land had fallen in love, then the quake hit, and all he knew was her town was gone. >> literally come hell or high water i was getting into that damn town. >> that's where he headed, right into that hell, willing to risk his life to try to save hers. >> fires on the hill, fire on the water. >> could he get there in time? >> i never loved someone like i loved georgia. ♪ >> welcome to "dateline." it's an epic love story, a young man from small town indiana heads to japan to teach. there he meets a beautiful woman from a land nearly as far away and they fall in love. but soon this young couple finds themselves in the middle of one of the biggest natural disasters

in recent memory, with whole towns being wiped out, would they survive? here is keith morrison with "swept away." >> who can say what lurks out there past the horizon, waiting impersonally, utterly at random, as thousands of lives tick to their unthoughing ends. and simple coincidence, a young man from middle america made a single decision. >> could you imagine back there in indiana that you're about to make your life flip on its head? >> no, never. >> how could he know that on the other side of the world a young woman made exactly the same decision or that they'd meet practically on the eve of one of the biggest natural disasters in recent memory? or how could he know that in the middle of disaster he'd lose her. >> i wouldn't know what i would do without her.

>> so coincidence, love, disaster. there is no fairness about these things, they just are. zach brannon turned 23 in 2010. had just picked up a degree in history from a college in indiana, no idea what to do next. and then he saw an offer for a job in japan, a two-year stint teaching english to elementary school kids, no japanese language skills required. >> why japan of all places? >> i don't think there's any rhyme or reason to it. i think it was just offered to me and i jumped on it. >> the town they sent him to in japan called kuji, a long way from his hometown of nashville, nashville, indiana. on sundays he skyped with his parents john and terry. john is a musician and terry a school guidance counselor. >> how did he seem to be doing?

>> it was rough at first, the language thing was the big thing. >> you were a stranger in a strange land. >> yes, yes. >> was it a lonely feeling? >> yeah, it was. but it was made better by the fact that there were other foreign teachers in town. >> along with the teachers, there was one other person, a volunteer who helped the foreign teachers adjust, a local english speaking businessman named kenji harayama. kenji, a pretty accomplished guitarist found out that zach was, too. >> i was amazed by his songs, his original songs, and also he played guitar very well. >> kenji pulled out an old gibson, handed it to zach. >> he said consider it yours while you're here. >> zach took that guitar to school trying to break the ice. >> i would play music for them. i think that helped break down the barrier a bit.

>> just three weeks in, overwhelmed by home sickness, he had called his parents. he had had enough. >> maybe as embarrassing as it is, i was actually crying, and i said to them, i can't do this anymore. i want to come home. >> we said, no, you made a commitment. you're a man. you gave your word. >> how hard was it to say that? >> it was really hard. >> it was hard. >> i may have probably hung up the phone a bit angry at him because it wasn't the answer i wanted to get. in retrospect, i'm really glad. >> zach tried to make it work. and then one night when the teachers got together there was someone new, another teacher just returning from a sunny vacation. >> it was this beautiful tan georgia coming back from croatia. >> 23-year-old georgia robinson, a recent university graduate herself from new zealand. she had been teaching and living in a nearby town on the coast called noda. in october, they all went to a

bless her heart, she had the flu and had her bathrobe on and was not feeling well. what a way to meet us. >> what did you think about this relationship with a girl so far away? >> we weren't putting that much stock in it. >> we were grateful that he had someone to spend time with. >> i was talking to my mom. she was like, so you really care for georgia, don't you? yeah. my mom got a bit choked up and said, what happens if you move to new zealand? i had to assure my mother and say, that's never going to happen, mom. >> come january, zach seemed eager to get back to japan. two months later, friday, march 11, 2011, the day before his father's birthday. >> i actually spent a lot of the day writing my dad a nice big birthday e-mail. i hit send on that e-mail and was talking to georgia on gmail chat, i'll see you after this rehearsal. >> boom.

>> boom. everything just began to shake. i was in an office chair with wheels. and so immediately as it started, the chairs began to slide. things began falling off the shelves. >> zach had never been in an earthquake. his co-workers knew this one was big. worried the building might collapse, they ran downstairs and out to the parking lot. but soon they were told it was okay, it was over. when the shaking stopped, the disaster was just beginning. there was a monster out there over the horizon called fate, and it was coming very fast. almost as soon as zach got back to his desk, warning sirens went off. even zach knew what that meant. if the tsunami was heading to his town of kuji two miles inland, what was it going to do on the coast in noda where

georgia was? >> what had happened to georgia? had anyone in her town survived the tsunami? coming up, zach knew he had to find her and a world away zach's parents still hadn't found him. >> this can't be happening. are you sure it's where zach is. >> when "dateline" continues. wid moderate-to-severe eczema, or atopic dermatitis, you never know how your skin will look. and it can feel like no matter what you do, you're itching all the time. but even though you see and feel your eczema on the surface of your skin, an overly sensitive immune system deep within your skin might actually be causing your eczema. so help heal your skin from within. with dupixent. dupixent is not a steroid, and it continuously treats your eczema even when you can't see it. at 16 weeks, more than 1 in 3 patients saw clear or almost clear skin, and patients saw a significant reduction in itch. do not use if you are allergic to dupixent.

friday morning, march 11, 2011. in nashville, indiana, john and terry whitcomb had barely had a sip of their morning tea when the news jolted them awake. >> this is a very powerful earthquake. the images are stunning out of japan. >> an epic earthquake hit northern japan, 9.0, near the top end of the richter scale. then a huge tsunami crashing up the coast. it was like watching a disaster movie, this one horribly real. and john and terry's son zach was now right in the middle of it. >> what did you think? >> unreal. this can't be happening. are you sure it's where zach is? are you sure it's in the same region? we were looking at maps, and everything was pointing to, yeah, it's exactly where zach is. >> we just prayed. >> enormous waves you see here

were hitting noda and kuji, the towns where zach and georgia were teaching. the frantic calls began, to no avail. >> what happened when you tried his phone? >> it would say all circuits are busy and you'd get a busy signal. >> then the minutes went by. >> uh-huh. >> then an hour and two hours. what did that feel like? >> hell. >> as a parent, you never think, oh, my child has been killed. you don't think that. you just wait. you just wait and pray for the best. >> remember, zach had wanted to come home months earlier, but terry and john had encouraged him to stay, to live up to his commitment. >> how much did you beat yourself up about that? >> i did. >> seemed right then, but now? >> the helplessness of we're way over here and there's not a thing we can do. >> georgia's family in new

zealand including cousin chelsea were just as scared and just as helpless. >> one of my friends got a text that said there had been a massive tsunami in japan. obviously we all freaked out because georgia was over there. >> they turned on the tv and saw images from noda, the little coastal town where georgia was based. >> it was unrecognizable from the images she had sent to us. the buildings were destroyed, there was debris everywhere. >> and georgia, though they tried and tried, was unreachable. >> we really thought that she had gone, kind of lost hope i guess. >> back in indiana that night, the news ever worse, john turned on his computer and read that last e-mail from zach. >> he sent it literally ten minutes before the earthquake hit, birthday greeting. >> and said what? >> happy birthday, love you. >> it said much more than that, though.

>> dearest rocken' poppy, happy birthday. whoo-hoo, the big five-0. the more and more time we spend apart the more i realize how amazing of a father and friend you have been to me over the years and have always given me a perfect example of how a man an husband is to treat a woman and his wife. i was thinking, god, is this the last thing i hear from my son, you know. >> and it's that. >> yeah. >> saturday morning, more than 24 hours since they had any communication from their son -- >> by 8:30, we still hadn't heard anything. we still woke up to even more horrible images and then had time to think about the death tolls and all that. it was just compounding and compounding and compounding. >> and then about the moment all seemed lost, another e-mail arrived, not from zach. it was from kenji, the volunteer mentor in japan, just a few

words, and they meant everything. >> brannan son survived. >> basically that was all it said. >> what was that like? >> of course we wanted more details. >> it was a relief. >> zach was alive. all they needed to know for now. but georgia, still no word. while his parents worried about him at home, zach was riding out the chaos in kuji. >> i wasn't really sure what was going on at first. >> after the shaking stopped, zach and his co-workers moved to the top floor of city hall, a crow's nest with a view of the whole city and the coastline. >> if something is going to happen, this is where you'd see it? >> yes. >> then he saw it. something about the rivers that split the city and normally flow out to the sea. >> the river was beginning to flow in the opposite direction.

the water began to change color as well, began going from this bluish color to being very murky. >> even four stories up, zach could hear the roaring river. >> it went from having small debris like trees and other rubbish that was around the harbor and stuff coming in to boats and to vehicles -- to much larger and much more substantial things. >> cars and things coming along -- >> yeah, must have been picked up along the coast. >> that is getting scary, right? >> yeah. >> of course, zach hadn't seen the footage that everybody outside the country had seen, towns wiped off the map, thousands missing. he couldn't know how bad it was. >> did your mind turn at all when you were up here to what's going on down there where georgia is? >> i hoped she would be doing the same thing that i was, that she would be in a safe location. >> a safe location? was there such a thing where georgia was? as the water around him began to

recede and zach and his co-workers came downstairs, he realized everybody was incredibly quiet. >> people's expressions had changed so drastically to these looks of genuine fear, that's when i thought i, myself was scared. >> now he understood. if the wave got as far as his town further inland, it had to have hit georgia's town right on the coast. what happened to all those people there, to georgia? suddenly he knew he had to find this girl, just had to. >> i wanted to see her, and i wanted to comfort her as well. >> no idea what would be waiting for you at that end? >> no, not the slightest. >> there's a moment in some lives that defines everything that comes after, the tests, the trial. this was zach brannon's test, to pass or fail. coming up -- >> i never loved someone like i

loved georgia. >> but sometimes love doesn't conquer all when "dateline" continues. ♪ ♪ let your perfect drive come together at the lincoln summer invitation sales event. get 0% apr on select 2018 lincoln models plus $1,000 bonus cash. stop fearing your alarm clock... with new*! zzzquil pure zzzs. a drug-free blend of botanicals with melatonin ...that supports your natural sleep cycle... ...so you can seize the morning. new! zzzquil pure zzzs.

stay with their families until their 40's. keith morrison (voiceover): zach brannon didn't fully comprehend how bad it was. [crashing] the tremendous earthquake and the deadly wall of water that followed it was snuffing out more than 18,000 lives. tens of thousands of homes, whole towns

were being swept away. but zach didn't know that yet. i just wanted to find georgia, my best friend. and also i just wanted to make sure she was all right. keith morrison (voiceover): zach kept telling himself she was all right. newda, this small town on the coast where georgia lived, was protected by massive concrete sea walls and barriers. so your first thought wasn't, oh god, she's in trouble. it was more, thank god there's a wall. yes. yeah. it's there, there's just no possible way that it could have gotten over that. how did you find out that you were wrong? well, i decided-- i just left. i left work. keith morrison (voiceover): back in indiana, zach's parents, relieved their son was alive, got another email. zach was going to look for georgia. now a whole new set of concerns like i wasn't exactly sure where she was. so once we figured that out and we looked it up on the map, well, it wasn't far away.

but we just-- it was even close to the coast. it was closer to the coast. wondering what he might find. john whitcomb: yes. terry whitcomb: and he was over there by himself, you know? and what would he do if he didn't find her? you know, it was just it was all those things. keith morrison (voiceover): zach hopped in his car and began the 8 mile drive down the winding road from kuji to newda. as i come down the hill, i start noticing people are walking on the side of the road. no cars but they're-- they're just walking. whole families walking. and i just thinking to myself, that's odd, you know? that's strange. as i got closer, i could see what looked like to be a house on its side just in the middle of the road. i was really confused because where were the tsunami walls? keith morrison (voiceover): police had set up a barricade.

and beyond it, what did you see over there? zach brannon: it was just complete-- complete destruction, you know? there had been like for a lot of the houses, they're heated with kerosene. keith morrison: yeah. so kerosene tanks had been knocked over throughout the tsunami. and because of the downed power lines, actually sparked fires. there's fires on the hill, fire on the water. debris everywhere. yeah. so i mean, it was a-- just a complete scene of destruction really. keith morrison (voiceover): zach, almost in shock, walked toward the barricade blocking the road. there was a police officer and he just said to me. dangerous. no. and just kind of began kind of trying to escort me back towards where i had parked my car. keith morrison (voiceover): so zach got in his car and drove back to kuji. trying to tell himself it would be ok. that georgia was fine. though the scene behind the barricade was chaos, disaster. it was obvious that there were many casualties.

it was pretty clear. how many? it was impossible to know. but zach understood, as he was turned away by the guard, that one person's anxiety could not be allowed to trump public safety. and yet, at that very moment he understood with absolute clarity, he had to find out what happened to the girl behind the barricade. he had to. if she was alive or dead or injured. he had to because she was the love of his life. you sent message after message by text. zach brannon: in vain. you know? knowing that they weren't going through but just hoping and you know, little messages of encouragement. i love you. i hope everything's all right. i'm going to come look for you. you know, i've tried. just know i'm coming. what were you thinking? i wouldn't-- i wouldn't know what i'd do without her.

guess that's the first time you really had to confront it in a serious way. right? zach brannon: yeah. i had a-- i had never loved someone the way i loved georgia. and so i-- i guess i just hoped that she is going to be all-- you know. she was going be fine. i was going to-- probably didn't sleep much that night. no. no. keith morrison (voiceover): the aftershocks went on all night. so did tsunami warnings. so you're thinking, is there going to be another tsunami coming through? you know, it's-- so no, i didn't really sleep.

keith morrison (voiceover): by 5:30am, so i didn't really sleep. >> at 5:30 a.m., he knew what he had to do. he left a note on his apartment door just in case georgia made it there. >> and i said, georgia, i'm coming to look for you. if for some reason you make it into kuji, stay here. if i haven't found you by sundown, i'm coming right back here. so know i'm coming back.an >> and then he got in his car again and headed toward the coast. >> and i just decided, literally come hell or high water i was getting into that damn town. >> but how? he'd certainly be facing hell and high water, but perhaps the biggest problem was the japanese army blocking the road. coming up, was time running out for georgia? had zach lost the love of his life? >> that feeling that she's not

japan, zach brannen approached the barricade outside georgia's town noda, determined to get past it, no idea how. >> i parked a little further out this time and started walking in, and they still had the police officers and the defense force there with their roadblock, but i noticed what looked like to be a group of locals with shovels and other gear, i'm assuming to go in to start clearing paths to the town. so i thought, that's my way in. >> the civilian volunteers seemed to have official permission to get in and clearly knew where they were going. >> so i just pulled my hood up and hopped in line with them. at that point no one was really kind of looking around. >> he slipped past the police line, followed the group up a path away from the main road. he knew where he'd go first, if he could. >> so your first destination was her apartment. >> yes. hoping id find her sitting there on the floor reading a book.

>> the path led up a hill past this shrine, descended back down to a horrific scene. noda was almost unrecognizable. >> there were these massive walls of debris, houses toppled over, boats, anything you can imagine. metal electric polls just bent as if someone has just come through and just -- >> but he knew georgia's place was on a hill. if she had gone there before the tsunami hit, she would be all right. but when he got there -- >> no sign that she was there. everything was still left exactly the way we had left it from the previous morning when we both went to work. >> as we went back outside, zach could see down into the center of town. that's where georgia's office was, where she was when the earthquake hit, and what he saw chilled him to the bone. >> what i could see of the central part of the village that was so destroyed, in my mind, i just could not see how --

>> nobody is surviving in that city building. >> yeah. >> shaking that from his mind, zach thought georgia might have gone to help out at one of the three schools where she taught. when he got to the kindergarten, his heart sank. >> the kindergarten was completely gone. >> wiped away. >> yeah. all that was left was a bit of the fence and some of the foundation. >> a kindergarten that would have been occupied? >> i had hoped not. >> later he found out those children were safe, evacuated before the tsunami hit. but now zach went to another school, found a group of teachers huddled in their office. unable to speak japanese, he passed around georgia's business card with her photo. >> i went in and kept asking, georgia sensai, where is she? have you seen her? >> they had not. but they did give zach some hope.

>> they said junior high, junior high. i take that, oh, she's at the junior high. >> so zach sprinted there, made his way to the teachers' room. >> i asked them, you know, have you seen georgia? they said they had not seen her, and i kind of lost it at that point. >> zach staggered outside, out of options, his despair now total. >> what was happening in your mind? >> just feeling so lost, that feeling that i've been trying to suppress, the feeling of she's not all right. it began growing in size immensely as each minute went by. >> one of the teachers came outside to comfort him with a cup of tea. >> telling me, it's okay, it's okay, it's okay.

hugging me and patting me on the back because i'm crying. yeah. >> then, out of nowhere, a van pulled up. two men hopped out. zach recognized one as a colleague of georgia's. they didn't look happy. zach tried to ask them. georgia, where is she? where is she? they didn't say -- because they spoke no english and i spoke no japanese, just pretty much like let's go, pointing to the van and just pushing me into the van, you know. >> they were taking him to city hall. >> as you were being driven in that van, did you have any idea what they were driving you to see? >> no. >> did you know they had been taking bodies to the city hall? >> no. >> didn't know that? >> didn't know. >> city hall had, in fact, become the temporary morgue. was that where he'd find georgia?

could eat which included lots of beer and saki on hand. >> and music. zach and kenji got out the guitars, tried to shut out the world. >> to kind of give ourselves some sense that everything was all right, you know? >> then cell phones chirped back to life. >> so everyone frantically had their phones out, sending e-mails to our families, being able to tell them that we're okay. >> back in indiana zach's parents finally got the news they had been praying for. >> it took me hours and hours, but i found her and she's alive. so the first thing i did was call brenda, georgia's mom, and she was in bed. she wasn't asleep. she was trying to sleep. i said zach found her. she's alive. and she just screamed and started crying.

>> mom came in and told me that zach had found her and she was safe and alive. that was the most amazing feeling i've ever experienced. he was very brave for what he did, very brave. but you do that for people you love. >> the danger wasn't over, of course. we all know what came next. >> you find out he's okay, she's okay. now what? >> fukushima. coming up, a different kind of aftershock. >> he said, have you checked your e-mail yet. i have said no. he said why don't you guys look at your e-mail together. i said, oh, zach, what now? >> when "dateline" continues. what sore back? what bum knee? advil is relief that's fast strength that lasts you'll ask... what pain? with advil

welcome back, i'm natalie morales. in the aftermath of japan's devastating earthquake welcome back, i'm natalie morales. in the aftermath of japan's devastating earthquake and tsunami, zach rushed into the chaos to find his girlfriend, georgia, alive and well. the couple wasn't out of danger, yet. here with the conclusion of "swept away" is keith morrison. the fukushima nuclear disaster. >> rescues damaged by the power plant. >> nuclear armageddon. the president was calling for americans to get out.

>> yesterday, we called for an evacuation of american citizens within 50 miles of the plant. >> we were seeing on the new, it is melting down. it is a matter of time. they can't stop it. >> it could affect the entire country, the entire earth. >> reporter: zach thought the worst was over. >> you never think you could experience a tsunami and earthquake now it's the meltdown of a power plant. >> we wanted him to come home. here we were the ones saying you wanted to stay, there was a commitment, but there was no travel anywhere. >> zach got a call from a u.s. air force officer. >> he said, we'll take you to the air force base and fly you to a safe location. >> reporter: what did you say? >> i said, you know, i actually lied and said georgia is my

fiance. i said she is a new zealand citizen -- >> reporter: can i bring her along? >> right. he said sorry, we can only offer it to u.s. citizens at the time. >> reporter: they were 200 miles north of fukushima. they began to feel the danger from the radiation subsiding, so they stayed, even helped with the clean up. then, about a month later, funny how these things go. zach and georgia got another shock. another life-changing development. zach told his parents about it during one of their regular sunday phone calls. >> he said, have you checked your e-mail yet? we said no. he said why don't you look at your e-mail together. i said, oh, zach, what now? >> reporter: after all the worry

and dread they experienced over their son's time in japan, zach's parents weren't quite prepared for the next bit of news. >> we open the e-mail and there's an ultrasound picture. >> reporter: a baby was on the way. >> we were literally speechless. one of the few times in my life we were speechless. >> we nicknamed it baby bean because it looked like a bean. >> it just, it felt right, in a way. we were obviously in love and the timing wasn't amazing, but it happened, so, let's just go with it. >> reporter: still, it was one last step. zach hadn't been quite ready to take it before, but when he came home to indiana to see his family. >> i was in indiana in june. my mom and sisters went with me

and we went engagement ring shopping. >> reporter: did he intend to do that? would he have without a push, do you think? >> i don't know. i know i said, would you marry her if she wasn't expecting a baby and he said yes. i said she needs to know that. she needs you to ask her to marry you, not be expected that you are doing the right thing. yeah, maybe i did push him. >> reporter: chen zach went back to japan, he was ready, or so he thought. georgia met him at the train station. >> as we were walking to the car, i don't know, i said you have to stop. >> i was like, what are you doing? it's freezing. let's get in the car. let's go. he said, wait. all of a sudden, he turned around and he's shaking but he's holding a ring box. >> i got down on my knee and i

just said, i love you and i want to spend the rest of my life with you. i don't care if it's in japan, new zealand or siberia, i want to spend the rest of my life with you. you know, will you marry me? >> i said, yes, of course. i had to put him out of his misery. he looked like he was going collapse. >> so, i was engaged. we didn't know what we were doing from there, but we were having a baby. >> reporter: you got married twice? >> we did, yeah. >> reporter: two weddings. the first in indiana. the second one in new zealand. there was a special guest at that one. 2-month-old sebastian. after promising his mother it was never going to happen, sure enough, zach and his family now live in new zealand. he works for the government,

georgia at a recruitment agency and sebastian is busy growing up. in 2014, we brought them back to japan for the first time since it happened. >> my name is georgia. >> georgia! ahh! >> this teacher and her students knew about georgia and zach. many here looked upon their story as one positive thing that came out of that horrible tragedy. do you ever thrks is a totally unfair question, do you sit together at night and say, boy, if it hadn't been for that day, would we be here? would we have is bastien and be in this life together? >> all the time. >> if somebody told me you would be living in wellington -- >> married to an american -- >> marries to a kiwi with a 2-year-old son -- >> i would have said you are

crazy. >> would have thought they were crazy. could have never imagined this. >> reporter: helped by an earthquake, tsunami and who knows what else. >> yeah. yeah. >> that's all for this edition of "dateline." i'm natalie morales, thank you for watching. good morning. i'm dara brown in new york at msnbc world headquarter. it is 7:00 in the east, 4:00 out west. the report says white house lawyer don mcgahn is cooperating fully with robert mueller's investigation. >> mcgahn is trying to save himself because trump would throw him to the fish if he could. >> is he telling the mueller team too much? >> the mueller team is panicking. they know they don't have a case. there was no collusio
