from new york city, this is "nightline" with dan abrahams. good evening, and thanks for joining us. for over 20 years, woody allen has lived under a cloud of suspicion, and tonight, he's hoping to clear the air. responding angrily and defiantly to allegations that he molested dylan farrow, the daughter of his ex-partner mia farrow, in 1992. last week, the now 28-year-old dylan recounted in "the new york times" what she says are the details of the horrifying assault. tonight, allen insists that's a vengeful, fabricated smear. here's abc's juju chang. >> "of course i did not molest dylan." tonight, that flat-out denial from the world renowned director, answering charges for the first time in 20 years. "i loved her and hope one day

she will grasp how she's been cheated out of having a loving father." and he didn't stop there, going on to place blame querrey on mia farrow. one must ask, did dylan even write the letter? or was it at least guided by her mother? the famously reclusive director speaking out to dylan farrow's open letter in a blog in "the new york times" website. >> this year cecil b. demille award recipient is many things to many people -- >> reporter: dylan broke her silence after woody allen was honored at this year's golden globes, accepted in his absence by his long-time friend and leading lady, diane keaton. >> he's made 74 movies in 48 years. in her letter, dylan describes in detail what she says she remembers happened to her. what's your favorite woody allen movie? before you answer, you should know when i was 7 years old, woody allen took me by the hand and led me into a dim, closet-like attic on the second floor of my house. he told me to lay on my stomach

and play with my brother's electric train set. then he sexually molested me." it's an allegation that allen has always denied. >> these totally false and outrageous allegations have sickened me. >> reporter: abramovitz was his lawyer. >> his reaction to dylan's letter is overwhelming sadness. it revives the fight that he had with mia farrow 20 years ago. >> reporter: it all began when woody allen fell in love with another of his leading ladies, mia farrow, back in the '70s. over the course of 12 years, they had three children together, two adoptive, one biological, in addition to mia's other adopted children. farrow was allen's artistic muse in many films including the classic "hannah and her sisters." that collaboration came crashing down during the filming of "husbands and wives." >> i thought it was a good idea to have a baby. >> i don't think it's such a good idea. >> why? >> reporter: that's when mia

discovered six naked polaroids of her then 19-year-old adopted daughter soon yi on woody allen's fireplace mantel. the scandal became a prolonged tabloid obsession. in the midst of the storm, mia went back on the set of "husbands and wives" to film their final scene. >> you were so beautiful in that black dress. really. >> don't do that. >> reporter: soon yi movedy allen's house, and within a few years they were married. the breakup hit the entire family hard. "vanity fair" writer spoke extensively with the farrow family last fall. >> the soon yi revelations were absolutely devastating to this family, according to the eight children i spoke to. because here he was, the de facto dad in the family for a long, long time. and so the fact that suddenly, their sister was sort of -- betrayed the mother and ran off with woody and he didn't act like anything had gone wrong. >> reporter: perhaps no one was more affected than 7-year-old dylan. a few months after the split on

august 4, 1992, dylan says allen took her to that attic room in farrow's country house. >> and did she tell you explicitly that she was molested in the attic? >> she told me that she remembers very clearly what happened to her in the attic and what she was wearing when she got there and what wasn't on when she left. so then she told me, my advice to the 7-year-old dylan today would be, -- be brave, testify. >> so she told you explicitly that she had been molested. not just that she was made to feel uncomfortable. >> she told me that she was made to feel very uncomfortable. >> mia farrow videotaped dylan's account of what happened and told the family's pediatrician, who by law had to alert the authorities. connecticut police launched a criminal investigation, which included an independent review by the yale new haven sex abuse clinic. >> after a six-month exhaustive investigation, that group concluded not only that the molestation did not occur, period, but they concluded that it was caused by either mia

farrow coaching dylan inappropriately, or dylan's inability to distinguish between fantasy and reality. >> reporter: criminal charges were never filed against woody allen, but the state's attorney who was in charge of the investigation at the time issued a statement saying he felt there was probable cause to charge the legendary director but he chose not to in order to spare dylan. >> i spoke to the prosecutor today and his sense was that, well, he kept saying "i stand by the remarks that i made that many years ago." but that with the probable cause, he -- it wasn't that he felt that no criminality occurred but that he didn't think dylan could make it through a trial. and that for her sake, he wouldn't press forward with a trial. >> i know that's what he said, and i think we brought him to task at the time for making an inappropriate statement like that. he either brings a case or he doesn't bring a case.

>> reporter: but allen lost the custody battle and an appeal. he was only allowed supervised visits with the three kids he had with farrow, and in a withering 32-page ruling the custody judge called allen a willfully inappropriate parent. he even cast doubt on some of the conclusions of the yale new haven center report, saying that the judge wasn't sure that the evidence conclusively proved no sexual abuse occurred. all of thf left a residue of doubt over what exactly happened that day. a doubt that was brought to the surface again this awards season. >> here's to woody. thank you. >> many observers are saying that dylan has nothing to gain by all this, why would she lie? >> i don't think she's lying. i think that dylan honestly believes this happened. i think that it is a function of the fact that she was used as a pawn in the fight between mia and woody. one doesn't become a pedophile overnight. you either are a pedophile or you're not a pedophile. >> reporter: since dylan's open

letter in the new york times, the battle between mia farrow and woody allen is being refought on tv. >> you don't have any comment on dylan's letter? >> reporter: this photo from the day dylan's letter went viral, allen and his two adopted daughters with soon yi, swarmed by the press. >> is woody a good father now? >> i think he's a marvelous father. >> i got to see a little bit of the dynamic with his kids. >> dr. robert whitey who made a four-hour series on the famously reclusive filmmaker and recently spoke with a surprising allen defender, his oldest adopted son with mia. they had been estranged for years. last week in "people" magazine, moses came to his father's defense. of course woody did not molest my sister. she never hid from him until our mother created the atmosphere of fear and hate towards him. >> i spoke with him personally when i was writing my piece for "the daily beast." he uses brainwashed without hesitation. fairly recently he reached out to woody, apologized and said,

let's get together. woody was so happy to have one of his sons back. and woody and soon yi are enjoying a wonderful relationship with moses right now. >> reporter: in that same "people" magazine article, dylan herself responded saying, "my memories are the truth and they are mine and i will live with that for the rest of my life. my brother is dead to me." as for the allegations that mia manipulated her, dylan strongly objects. "my mother never coached me. she was distraught when i told her. she was hoping against hope that i'd made it up." and late tonight, an impassioned response from dylan farrow to abc news. "for 20 years i have never wavered in describing what he did to me. woody allen has an arsenal of lawyers and publicists. but the one thing he does not have on his side is the truth." with the oscars just weeks away, some hollywood insiders suggest this may cast a shadow over allen's most recent movie. >> do you think this might have an impact on how his career is perceived? >> i certainly hope not. i would assume that people who

participate in the voting for the oscars do so on the basis of the art itself and not the personal conduct of anybody. >> the achievement i'm going for is to try and make a great film. >> for "nightline," i'm juju chang. >> seems this very emotional war of words is not going to end tonight. next, for young boys growing up in a tough neighborhood, you might not think the best way to stay on the straight and narrow would be to join a rowdy group of bikers. but could it be good for them? ♪ ♪ ♪ ♪ (bag shaking) (vo) bring the thrill of the catch...

for boys living in a tough neighborhood, staying out of trouble can be a challenge. joining a biker group called the 12 o'clock boys may not sound like a solution. after all, they can be rowdy and at times end up on the wrong side of the law. but as abc's byron pitts found when he headed back to his own hometown, this controversial crew may also be the best option for many looking for an extended family.

>> reporter: inner city baltimore, my hometown, where in too many neighborhoods drugs and violence are just the facts of life. meet the street bikers of baltimore. weekend warriors on two and four wheelers. on sundays they roam the city as if it's their private playground -- racing, weaving, acrobats with attitude. they call themselves the 12 o'clock boys. the police and many others view them as a public safety hazard. >> i believe we lose at least 10 to 15 lives every summer in reference to dirt bikes. >> reporter: but for the bikers, riding is often the safest option these streets provide. >> you learn the right way to do all the wrong [ bleep ] in baltimore city. hustling, shooting, selling drugs. killing some [ bleep ]. one of the first things you see that you actually want to do is ride a dirt bike. that's one of the first things you see that's positive. >> reporter: and that's how 12-year-old taekwon ford sees

it. his nickname is pug. street riding is his version of the the boy scouts. being part of the pack is his dream. >> why do you want to be a 12 o'clock boy so badly? >> because, like, it's fun. >> what do you feel? what do you think when you're riding? >> i feel powerful. i feel like a superhero. i feel like i'm on top of the world. >> they get on that bike, they feel powerful. whatever's going on in their life is all gone. you can escape and ride. >> reporter: the group is named after their trademark maneuver. speeding down the street with their front wheel pointing straight up, 12:00. they're the subject of a controversial new documentary that bears their name, "the 12 o'clock boys."

>> we need to catch up because they're going to go down the road again. >> right, i know. >> reporter: the film follows pug for three years. from precocious 12-year-old who loves animals to an edgy, often angry teenager hardened by circumstance. pug's mother coco brown struggles to raise him on her own. >> you can get locked up for certain things. you need to get yourself together and stop worrying about bikes. bikes is not everything. >> reporter: but in many ways it is the bikers who are raising him. >> it takes a village to raise a child, it really does. she can raise pug by herself but she shouldn't have to. one person trying to raise [ bleep ] like that is a lot. >> are these older guys mentors to you? >> yeah, they taught me stay in school, do all my work, pass all my classes. they just taught me focus on school, don't worry about bikes all the time. >> i grew up in baltimore. when i think about the men who mentored me, they're men in my church. >> but for someone like pug who needs to rebel, he's working against something. he's seen enough by a certain

age that he's got a kind of hard edge. and it's going to be an unconventional way of growing. it has to be through rebellion. >> reporter: director nathan started following the group for a project as a college student in baltimore. >> the 12 o'clock boys have been called a fearless pack, a gang, menace, troublemakers. what would you call them? >> the rebels. i think that they're also mentors. they're also children. it's actually kind of a way of edification for a lot of kids in baltimore. it's kind of like the boy scouts or something. in the context of what gangs can really be in baltimore and what violence can really be and what crime can be. >> reporter: for a city its size, baltimore is one of the most violent crime and drug ridden in america. there were 235 murders last year. 29 so far this year. you say that baltimore isn't safe. what do you mean? >> you got to be careful out there. people get shot, sometimes for no reason. just being at the wrong place at

the wrong time. >> have you seen the kind of violence you're describing? >> in 2007, i think, we was all walking and this boy just came out of the alley with a hoodie on and this other boy, he shot him and he got to the alley and dropped. i guess he was dead because he wasn't moving. >> what's that do to a young person, to do you, to see those things? >> i started to get used to people just walking around with guns and i never looked at them as a role model. i always looked up to the bikes. >> reporter: but there are real dangers here. bikers have been severely injured. some have been killed. baltimore police can do only so much. officers usually don't chase the bikers for fear of accidents. >> you don't want to risk the lives of innocent people by chasing them unless they committed a violent act. but at the same time, the act of them riding around doing wheelies at high speed is a violent act in itself.

>> reporter: when the violence on the streets of baltimore can take your life at any minute, by comparison, riding a bike doesn't seem so dangerous. >> you've got your whole life to see the bikes. >> no. >> why not? >> tomorrow is a day not promised. could die any minute. >> as an old guy, i think sometimes children shouldn't think that way. shouldn't have those concerns. >> i used to think nobody can never die, as i was growing up. i see people getting shot, murdered, stabbed. you never know when your time is up. >> reporter: for pug and children like him, the road out of baltimore is lined with more obstacles than even the most skilled 12 o'clock boy could ever maneuver easily. for "nightline," i'm byron pitts in baltimore. >> 12 o'clock boys is now in limited release in theaters nationwide and on itunes. next, from the eccentric to the just weird. the olympic opening ceremony, plus an epic fail.
