Where to Watch Monkey Shines (1988)

Once there was a man whose prison was a chair. The man had a monkey, they made the strangest pair. The monkey ruled the man, it climbed inside his head. And now as fate would have it, one of them is dead.

A quadriplegic man is given a trained monkey help him with every day activities, until the little monkey begins to develop feelings, and rage, against its new master and those who get too close to him.
