Dreams Don't Die (1982)

Two young kids in love, one young graffiti artist and the other a foster-child, find trouble on the mean streets on the other side of the river in New York City. Officer Charles Banks finds young Danny tagging subway cars and then catches Teiresa selling drugs for another misled teen, Kirk. The officer, instead of turning both of them in, gives both teens a chance to make more of their lives together. Changing their ways turns out to be more challenging than first thought.
