The Evil Within

This is a decent episode. Rod Steiger is a research scientist. He has developed some substance that affects the personality, that unleashes the id impulses. His resentful wife damages his body of work, destroying his samples and burning his research notes. She has been affected by the spillage of some of the stuff on piece of pie she is eating. Her baser instincts take over and she becomes a veritable beast. Now it's up to Steiger and lab assistant James Dean to try to recreate the work. Meanwhile, she become a vamp, acting in ways she has never done before, totally out of character. She vows to destroy him, but she, herself, becomes self destructive. This does have a kicker which is worth waiting for.
