Instinct

A gorilla expert apparently lost his wits in Africa and murdered two park rangers in a fit of rage. He is flown back to the U.S. and locked up in the psychiatric wing of an overcrowded prison, where he behaves and grunts like an ape and attacks anyone who comes near. An idealistic young psychiatrist befriends him, discovers his inner goodness and helps him.
