The Buddy System

A quiet school truant officer, Joe, uncovers a young boy's attempt to fake a residential address, and subsequently gets involved romantically with the boy's mother. The truant officer waffles between a sadistic relationship with his on-again, off-again girlfriend and the mother. When one of the officer's inventions takes off, he chooses the girl and shatters the friendship with the boy and his mother. (imdb)
