but first the "nightline" five.

good evening. thank you for joining us. as tv shows and movies push the boundaries of sex on-screen, a new movement has begun off screen in part because of the me

too movement. here's my "nightline" co-anchor, juju chang. >> what if i told you that i wanted you to [ bleep ] me right here right now. >> reporter: almost nothing is off limits in "euphoria." ♪ feel the morning on my face >> reporter: the gritty teen drama stars zendaya, and a web of young actors, portraying drug use and hard core sex among high schoolers. in one graphic scene turning what appears to be a brutal rape into an intimate moment between two sexually confused teenagers. >> don't do it again. until you ask me first. >> reporter: euphoria seems to revel in its dark, its dark, itd explicit life of a they define how much skin they

show and how much sex they engage in on-screen. >> it's amazing how much better the product is when the actors know they're going to work and are not going to be sexually assaulted that day. >> reporter: they are called intimacy coordinators, people who choreograph sex scenes, preplanning every embrace, every touch. how is being an intimacy coordinator like being a stunt coordinator? >> we are not actually having sex on set. there are ways to cheat that and do it safely with hygiene, sexual health, all of that in mind. >> reporter: alisha rodis helped create the group. they wrote the handbook for intimacy on stage and on-screen. there a there's physical health and emotional health. >> it's to make sure someone isn't being traumatized, that

someone isn't being harassed. >> reporter: we met up in manhattan, where her services are now in high demand, working multiple projects, including season three of "the deuce", centered on the porn industry in the '70s. >> they're the first tv show to pull knee and sme in and say we need something. we're going to figure out how this works together. >> reporter: after positive feedback from "the deuce." they require an intimacy coordinator on all scripted shows. >> it is covering your ass. on the other hand, they realize that they're like this is not for us. this is for the industry. they're all kicking themselves as to i can't believe we didn't think of this before. and my sense is that what made them think of it now is the # movement, known as me too, times up. >> absolutely. i don't think anyone had any idea how big of an issue it

really was. >> reporter: last year, rose mcgowan told me about intimate events she filmed while building her career, a string of nude scenes. >> it felt like what it really felt like, which felt like eck pos exposed and creepy. >> reporter: you said you cried afterwards. >> yeah. >> reporter: why? >> i have zero problem with nudity, but it wasn't my choice. >> reporter: it's an issue that's long plagued hollywood, balancing simulating sex with the toll it takes on actors. >> i did build this incredible bikini out of pasties. >> reporter: as sandra bullock explained her sex scene during "a time to kill." it can be overwhelming as jennifer lawrence explained in a round table for the hollywood reporter. >> i had my first real sex scene. it was very vulnerable.

you don't know how much is too much. you want everything to be real. >> reporter: but often it can be traumatic. in an op ed, salma hayek she was forced to do full frontal nudity. she added that she had to take a tranqui tranqu tranquilizer. kim masters has been reporting on harassment since the '90s. >> we've seen a pervasive culture of abuse and we still hear reports of abuse. it's been a matter of concern for a long time. but i find that the culture of hollywood is fru frustratingly w to change. >> reporter: these sets now so guarded we weren't even allowed to bring our cameras. why would it matter to an actor

to be eck posed xposed? >> it can be really scary to get out there and take your clothes off in front of people. and it just feels very vulnerable to be in that position. so these are our modesty garments right here. >> reporter: for blumenthal, a day at the office includes this treasure trove of modesty garments. >> we have an hibue. this is a stick-on strapless panty. so this one has adhesive. part of my prep with actors is i tell them how to put the nudity garments on. all the contents go in the pouch. >> reporter: why is it important to have choreography? >> it's important so actors can consent to where they're going to be touched before we do the scene. so when i work with actors, i make sure to talk with them about whether or not they're

okay with things like having their hair pulled happen. and then if they are, and especially if it's part of the choreography, we practice it in rehearsal. >> reporter: she says part of her job is to protect actors from being coerced into doing more than they agreed to, like legal agreements. give me an idea of the types of body parts. >> we can only see the upper right quadrant of someone's butt. we can only see the left nipple. >> reporter: how can a director end up being coercive? or bully an actor or actress into doing a sex scene or nude scene they may not be comfortable with? >> they can threaten them with stay it's a tv series, we're going to write you off the show if you won't do more nudity or sex for us. >> reporter: but it doesn't even have to be a direct threat. it can be an impolicity threat, no? >> oh, yes.

>> reporter: they are already making a difference, pointing to a violent scene in "the deuce." in this scene, basically, he assaults her, sexually assaults her. >> it's between a pimp and the prostitute. and it was very emotional scene. it was cold. it was painful. and someone said, you know, that's your last scene with gary, and they both started to cry and hugged each other. and i thought how awesome is that, that we just filmed this really gruesome, non-consensual sex scene and they're not in some traumatized place from doing this scene. >> reporter: this new age of consent, now extending beyond hollywood to broadway, and college theaters. >> let's make a circle and i'll explain these contraptions. i'm running a workshop.

it's a consent and communication workshop, how to consent and have the communication of working on scenes of inter in >> reporter: to usher in a new era of accountability. >> we need proper conduct in the workplace, more women, more people of color in the executive suites. >> reporter: for "nightline," juju chang in los angeles. up next, the price one woman paid for befriending a fake heiress. brain freeze! no, it's my teeth. your teeth hurt? sensitivity. i should do something about it. 80% of sensitivity starts at the gum line, so treat sensitivity at the source. new crest gum and sensitivity starts treating sensitivity immediately, at the gum line, for relief within days and wraps your teeth in sensitivity protection. ohh your teeth? no, it's brain freeze! crest. healthy, beautiful smiles for life.

glitz and glamour for one woman masquerading as an heiress ending up with her behind bars. now a friend who talks about falling under the spell of lavish lies. here's deborah roberts. >> she just was very impulsive and free spirited and charming. i really liked her. >> reporter: anna made an impression on everyone she met. were you sort of seduced by her and her behavior in some ways? >> i'd say yes, i was captivated by it. i was fascinated by her willingness to just challenge boundaries. >> reporter: claiming to be a german heiress with a $67 million trust fund, she talked her way into exclusive new york parties and nightclubs, which is how she met rachel williams in 2016, then a288-year-old photo editor at "vanity fair." >> it was a period of transition

for me and a lot of my friends. a lot of them were getting married or having babies, and i was excited to have this person who was available and ready to be my friend. >> reporter: the pair soon became inseparable, living the glamorous life of two young women in manhattan. why do you think she was able to walk into rooms and do what she wanted? >> to some degree because she's a young, white female. also a lot of it had to do with her specific charm. she seemed goodwilled. >> reporter: 25-year-old anna treated rachel to drinks and dinners at exclusive restaurants and even $300 a pop private fitness sessions. >> i liked her. we had a lot of fun together. >> reporter: but what rachel didn't knowsha her friend was living a lie. anna was actually a russian-born daughter of middle class parents, a hotel-hopping social

grifter, now behind bars for a series of wide-ranging scams across new york city. how do you feel about anna today? >> i believe she's a sociopath. >> reporter: rachel's speaking on camera for the first time about how she says her former friend betrayed her, a tale she recounts in her book, "my friend anna." >> i don't feel a lot of anger. mostly i feel like i would never like to cross paths with her again. >> reporter: in the beginning, rachel had no reason to doubt her big-spending new friend came from wealth, given her jet setting lifestyle and big ambitions. >> she wanted to lease this big building to house an art gallery. she referred to a family trust she had. which i didn't pry about but it formed my understanding of her. >> reporter: you figured she had money. >> yes. and that came out over time. >> reporter: in the spring of 2017, rachel tells us, anna offered an all-expenses paid trip to marrakech in a lavish

$7500 a night villa. >> it was shockingly opulent. >> reporter: your eyes must have been popping out of your head. >> morocco, that's where i was like, oh, i thought i understood your world, but actually, this is ridiculous. it was, i mean, it was amazing until it wasn't. >> reporter: that's because rachel says suddenly anna's credit cards mysteriously weren't working when it was time to settle up with the hotel. >> the managers began to pull anna aside and it was slowly escalating that there was tension between anna and the hotel. >> reporter: after a few days of hounding anna, the hotel had enough. >> they stood in our villa, and they were waiting for her to fix it. >> reporter: they want payment. >> yes, they want a credit card that works right there right now. they're done waiting. >> reporter: rachel says she's fearful of being stranded in a foreign country and offers her credit card as a temporary backup even though she can't

afford it. >> i leave early on friday morning. when i land, i get a text message that the whole bill is being billed to my cards. >> reporter: how much? >> $62,000. >> reporter: $62,000. how did you wrap your mind about that? >> it was such a complex, paralyzing moment for me. she owed me more money than i made in a year. >> reporter: back in new york, anna doesn't send rachel the money, instead making excuse after excuse. texting, i will get it sortedsoo you have it this week. rachel replying, i'm in serious trouble, anna, what friend leaves another person in this situation for this long? what is going on with you. >> i am late with my rent and my credit card payments. i'm in a lot of trouble. >> reporter: rachel's convinced she's been duped and goes to the authorities. in the summer of 2017, police arrest anna in malibu, california. >> if she did this to me and i was her friend, she'd do it to

anybody. and i wanted to protect other people. >> reporter: anna is charged with grand larceny, attand rcnd services. during the trial, prosecutors arguing she stole more than a quarter of a million dollars from hotels and a jet operator to fund a lavish lifestyle, anna's attorney saying anna is not a victim. >> i don't believe a criminal act occurred. she made a choice to put this on her credit card. >> reporter: rachel testifying, facing her former friend in court. >> when i did look at her, she was smirking at me. >> reporter: did it unnerve you? >> no, shockingly. i think understanding her for who she was, it caused her to lose her power, and she became no longer scary to me. >> reporter: in may, 28-year-old anna was convicted of eight charges against her, including grand larceny but found not guilty of defrauding rachel.

some of the jurors didn't feel sympathetic for your situation with anna. how did that feel for you? >> hoerks thoh, that was devast have shared so publicly something that was so deeply personal and painful for me was extremely hard, and then to have that come out as the take away was extremely upsetting. >> reporter: anna was sentenced to four to 12 years in prison and ordered to pay nearly $200,000 in restitution. as for that huge credit card bill. did you have to pay that money? >> ultimately, thank goodness, american express did protect me from the hotel charge. which was the bulk of the expenses. >> reporter: the story of the so-called soho scammer has caught hollywood's eye. anna sold rights to her story to netflix and shonda rhimes can't profit from it. the money will go back to those she scammed.

hbo purchased the rights to the story and are working on an adaptation. you've got a movie deal, this is now your opportunity to cash in. >> there's a lot of hard work turn what was hard and upsetting and world-rocking. it was a lot of hard work to turn that into a positive. when. >> reporter: when you look back on it, should you have known bet sner. >> i wanted to see the good in her, and i think's important to see reality. >> reporter: trust your gut. >> trust your gut. >> reporter: for "nightline," deborah roberts in new york. and next, a soldier springs a surprise, and everyone's on board with it, almost everyone. >> ah, my baby! my baby home! more migraine-free days. ou can do with
