Halloween 4: The Return of Michael Myers

Michael Myers, a psychopath who murdered sixteen people, was eventually captured by his own doctor, Dr. Loomis. After spending ten years locked up in a maximum-security prison, Myers is transferred, in a catatonic state, to the Smith's Grove Sanitarium. But inexplicably he escapes again in order to kill his only surviving relative, his niece Jamie Lloyd. Once again, Dr. Loomis will try to catch him.
