Stella does tricks (1997)

One of a brood of school-age prostitutes working the streets of London, Stella is a virtual prisoner of her sleazy, paternalistic pimp, Mr. Peters. Realizing that she must make her escape, Stella hooks up with Eddie, a young junkie, to confront the ghosts of her past and make a clean start. She soon learns, however, that escaping a past such as her own is precarious. Forced to turn one last trick, Stella seizes a perfect opportunity to wreak revenge on her pimp and finally gain freedom.
