Dog Run (2001)

In 1995, teen runaways Eddie and Miles are sent to New York City to deliver on a drug deal with the promise of easy money and a place to live. But when the deal falls through, they find themselves penniless in Tompkins Square Park in the East Village on the Lower East Side. They discover a vast underworld of abandoned buildings where kids live and are drawn into a world of sex, drugs, and survival.
