Other Halves (1984)

A Polynesian street-kid and a much older middle-class housewife are both incarcerated in the same mental hospital - she for attempted suicide and he for habitual crime. A friendship grows between them such that she offers him a place to stay upon his release. However, difficulties arise with his continued criminal activities and dependence on her for support - then his gang moves in with them. The film is based upon Sue McCauley's award winning autobiographical novel.
