In The Leech Woman,  Dr. Paul Talbot (Philip Terry) is searching for the perfect formula to make women look younger, when an elderly woman named Malla (Estelle Hemsley) comes claiming to be 140 years old. She also claims to know the secret to reverse aging, but the ingredients are in Africa. Paul is ready to throw the old woman out until she says that other doctors would test the powder before calling her a fraud.
