Discovering the secret to eternal youth has never proved to be so deadly as in the classic sci-fi thriller, The Leech Woman. Hoping to reverse the effects of aging, Dr. Paul Talbott (Phillip Terry) follows a mysterious tribeswoman (Estelle Hemsley) to Africa and convinces his neglected wife June (Coleen Gray) - an intended guinea pig - to join him. After the natives allow her to make the transformation, she escapes from the tribe and returns home to New York, a voluptuous recreation of her former self. Unfortunately, her beauty comes at a cost and cannot last without an unending supply of male victims.
