good evening. thank you for joining us. we begin tonight with the new development in a celebrity custody battle. it's a drawn-out and dramatic high society tale worthy of a

plot line on gossip girl. but for an actress who just bid farewell to her children, this is heartbreakingly real. here's linsey davis. >> reporter: gossip girl star kelly rutherford stunned and fighting back tears after losing a bitter custody battle in court, the judge ordering the american-born children to go back to monaco immediately to continue to live with their father, german businessman. this decision follows the father's accusation that she kidnapped the children when she disobeyed a monaco court order by not putting them on a plane last week. >> from the beginning i said i would fight for my children. i think most parents would. >> this was a mother refusing to abide by a court order and forcing the father to do something that he was loathe to

do. >> reporter: today rurterford was forced to say good-bye. their paternal grandmother taking the children directly from court to the airport. >> the children seem to be doing very well. they're clearly loved by both of their parents. >> kelly rutherford really managed to keep it together. she told the kids you're going to see papa. it's only when she left court that she appeared to brake down, leaving in tears. >> reporter: the actress known for playing lily vander woodson, a complicated, yet loving mother, now left to pick up the pieces of a real-life drama. six years ago when rutherford filed for divorce, she and her ex-husband were supposed to share custody, but when he was expelled from the u.s., the judge ruled that the children should live with their dad tim prafrl while he reapplied for a

visa, saying the best interests of the children will be served because the relocation plan for france is the only plan that offers the possibility of nearly equally parenting time while daniel cannot return to the u.s. but he has not reapplied for a visa. >> you have a father whose visa gets revoked. two parents who are both deemed to be good parents, an attorney for the kids who says the kids ought to stay here, and a judge determines that because the dad can't come to the united states that the kids ought to go with him? >> reporter: rutherford expressed her pain then on "the view." >> they're in france. i last saw them about a week ago. they were supposed to start school the next day. my little girl said i want to come home, mama. i want to come back to new york. >> reporter: rutherford says all the legal fees and trips to see her children led her to file

bankruptcy in 2013. all of this taking its toll as she told me in april. are you more frustrated or angry or sad? >> i could sit here and tell you how often i cry, not being able to take them to school, pick them up from school, dress them, smell them, hug them. >> reporter: and since then, she made claims that he had stopped her from visiting the children. >> i'd flown all the way over there. the kids had expected me to see them, i was expecting to see them. and he refused. >> he's been very generous about his allowance of access to her and the facilitating her access. >> reporter: last month, rutherford was in better spirits. >> it's emotional, it's incredible. we're all a little jet lagged. helena learned to ride her bike in the park yesterday. it was really exciting. >> reporter: after a court in monaco ruled that the kids should spend several weeks of summer vacation with her. >> their father has only let me

see them 11 days this year. >> reporter: kim kardashian tweeted, i don't know you, but as a mother i feel your pain. she even lobbied president obama to help her. the white house responded saying they're declining to comment on it, due to the ongoing legal proceedings. >> it's very hard for the kids and i. it's been kind of cruel in a way. because, you know, we just want to see each other and be together, they're very, very young. >> reporter: last friday, rutherford was supposed to return the kids to the custody of their father which she refused. >> none of us expected this to go on this long. i trusted the court that this was going to be temporary. i trusted their father that he would live up to his agreement that it would be temporary. and three years has not been temporary. >> it is a drastic measure. it means that the children are being withheld and their

whereabouts are unknown. >> reporter: in response, the lawyers invoked emergency jurisdiction, asking the judge to order her to return the children. >> she was not going to comply with the agreements that the parties had made. >> reporter: but today his attorney says he's thrilled with the ruling. >> he's a loving father. he's very excited to have his children back. >> i think when you look at the totality of this case, it's a total miscarriage of justice. she has been placed in a complete and total no-win situation. >> reporter: in your estimate arks does this saga continue? and when does this end? what's next? >> technically, they still have shared custody. the question's going to be, what happens as a result of this latest incident? is that going to change anything? >> reporter: rutherford and girsh will next face off in

september to discuss whether the kids can spend time with rutherford in the u.s. >> he would be well-advised to be concerned about allowing them to come back here unless proper protections were in place. >> reporter: an uncertain future for this fractured family. >> a move to monaco may be necessary at some point if she wants to spend a lot time with her kids. it's just a horrible situation. >> reporter: one that likely won't end anytime soon. >> it's not what i would have expected at all. and, you know, my kids have been through a lot. i've been through a lot. i'd like nothing better than to have this resolved for everyone's best interest. >> reporter: for "nightline," i'm linsey davis in new york. next, we found what just may be the craziest commute on earth. and a 90-year-old lady who does

it every single day. and doing good in sin city, why this unconventional ceo invested so much into the less flashy parts of las vegas. and ones you never thought you'd make. we help connect where you are. to places you never thought you'd go. this, is why we travel. and why we continue to create new technology to connect you to the people and places that matter. thiproof of less joint pain. and clearer skin. this is my body of proof that i can fight psoriatic arthritis from the inside out ...with humira. humira works by targeting and helping to block a specific source of inflammation that contributes to both joint and skin symptoms. it's proven to help relieve pain, stop further joint damage and clear skin in many adults. doctors have been prescribing

humira for nearly 10 years. humira can lower your ability to fight infections, including tuberculosis serious,sometimes fatal infections and cancers, including lymphoma, have happened, as have blood, liver and nervous system problems, serious allergic reactions, and new or worsening heart failure. before treatment, get tested for tb. tell your doctor if you've been to areas where certain fungal infections are common, and if you've had tb, hepatitis b, are prone to infections, or have flu-like symptoms or sores. don't start humira if you have an infection. visit humira.com and talk to your rheumatologist. humira. this is a body of proof! that gives you the power of a pc at inand fun of a tablet.ology i could turn it into a tablet and do my spreadsheets? i said fun of a tablet... exactly! upgrade to a 2in1 with intel inside. after a dvt blood clot.mind when i got out of the hospital what about my family? my li'l buddy? and what if this happened again?

i was given warfarin in the hospital but i wondered if this was the right treatment for me. then my doctor told me about eliquis. eliquis treats dvt and pe blood clots and reduces the risk of them happening again. not only does eliquis treat dvt and pe blood clots, but eliquis also had significantly less major bleeding than the standard treatment. knowing eliquis had both... turned around my thinking. don't stop eliquis unless your doctor tells you to. eliquis can cause serious and in rare cases fatal bleeding. don't take eliquis if you have an artificial heart valve or abnormal bleeding. if you had a spinal injection while on eliquis call your doctor right away if you have tingling, numbness, or muscle weakness. while taking eliquis, you may bruise more easily... and it may take longer than usual for bleeding to stop. seek immediate medical care for sudden signs of bleeding, like unusual bruising. eliquis may increase your bleeding risk if you take certain medicines. tell your doctor about all planned medical or dental procedures. eliquis treats dvt & pe blood clots. plus had less major bleeding. both made switching to eliquis right for me.

ask your doctor if it's right for you.

traffic jams, train delays. you may think your daily commute is stressful, but what if your only option for getting along was to zip along a high wire, dangling above a massive canyon. tonight we're heading to a remote part of china, in search of this remarkable sight. >> reporter: there is something different in the mountains of china. imagine this as your daily commute. for untold generations, this was the only way to cross the new john river. but in this new china of high-speed trains and choking pollution, these zip lines are disappearing. so to see the last of them, we decided to journey up to the remotest parts, it is the last

free-flowing river in asia that carves its way through the tibetan plateau and myanmar before emptying into the sea. this is a part of china i've never seen before. this is called "the first bend of the new river", and it is the most amazingly beautiful place i've ever seen. as we pass bridges and towns, the zip lines were actually hard to find. on our journey, we discovered men taking their annual bath in the volcanic hot springs, others offering to show me their huge, homemade cross bow. that's my first shot ever. bull's eye. these guys love me. the river cuts so deep that this area is sometimes known as china's grand canyon. it's getting more and more remote, which provides the farmers here with a challenge,

crossing the river. fewer and fewer people along the narrow dirt road, and suddenly we hear it. villager after villager suddenly arriving from across the river. we meet this woman. of course she doesn't speak a word of mandarin, so we recruit someone from the younger generation to translate. she has been crossing the river on the zip line since the 1930s. >> she's 90. >> reporter: you're 90, and you've been doing this since you were 10 years old. was it always bamboo? yes, they were bamboo until the 1970s. their only breaks, this. no one's ever been hurt? not even on the bamboo? never, she says. my dream is when i turn 90 years old like you i want to do exactly the same thing.

this zip line was built for them by the government. but even now their harnesses are makeshift and homemade. it's not exactly something you can buy at the stores. not only do they use this to get to work or shop, they also take their kids to school. this mop told us her son will not be allowed to cross the river alone until he is 10. our translator is a 17 year old and invites us across the river to see how he lives. and the villagers offer to give us a ride. woo-hoo! oh, my god! this is beautiful.

i was just really nervous when i started to prepare for it. i think once i held onto it, i knew it wasn't going to fall down. then once you start moving, it's the best thing. not to be outdone, these courageous, older, stronger women join in on the fun. who, like the grandmothers before him, grew up here. you live in a beautiful, beautiful place here. but it may be part of the last generation of zip liners. is it changing too fast? big changes, he says. when he was in primary school, this road wasn't even there. now it connects his village with a distant bridge. for now, the zip line is still the fastest way to get to the other side, to get supplies, jobs and school. however, even more change is coming. china's government is planning on building at least four new

hydroelectrical dams on the untouched river, although environmentalists have fought the dam and it has yet to get full approval. as we travel up and down the river, construction has clearly already begun. is that good or bad? better, he says, because they have transportation now so they don't have to walk for miles uphill to haul food and equipment. do you think your child, when you have one, do you think your kids could possibly ride the zip line? or do you think it will be gone by then? he say it is will be gone. does it make you sad? a little bit, he says. as for grand ma, she says she's going to enjoy this ride for as long as she can. unbelievable. she's 90 years old. i don't think my grandmother's ever done this.

ready? i'm bob woodruff for "nightline," soaring above the river in china. and next, we're meeting the perky ceo of a major company. he owns how many pairs of shoes? he said sure... but don't get just any one. get one inspired by dentists. with a round brush head. go pro with oral-b. oral-b's rounded brush head cups your teeth to break up plaque, and rotates to sweep it away. and oral-b delivers a clinically proven superior clean vs. sonicare diamond clean. my mouth feels super clean. oral-b. know you're getting a superior clean. i'm never going back to a manual brush. at intel, they make technology that lets a device be a laptop and a tablet, so you can put two in one. no, you can't. can. can't. can. upgrade to a 2in1 with intel. ♪
