The feature is called Pier Kids: The Life. Here's the premise:
Pier Kids, a documentary by first-time director Elegance Bratton, follows the plight of black LGBTQ homeless youth in New York City. The name originates from the youth population that congregates along Christoper Street in New York City's Greenwich Village and the surrounding piers during the nights and weekends. As many may be aware (but ignore), some of them sell their bodies for money, some of them are strung out on dope; all of them are treated unequally by a society that refuses to accept them, and refuses to help them.
Looks like a must see
