The Alligator People

A young wife (Beverly Garland) is abandoned by her husband on their wedding day. Distraught, she traces him to his ancestral home in the bayous of Louisiana, where, amid the swamps and deadly undergrowth, she discovers a terrible secret. Her husband was saved from death by an experimental medical procedure involving serum derived from alligators and now he's developing horrifying side-effects. She'll face any danger to help him, but soon discovers her love may not be enough. (official distributor synopsis)
