A man seriously injured in a plane crash is treated with an experimental substance taken from an alligator and he appears to be completely healed. But on his wedding day he gets a telegram from his doctor telling him that there are horrible side effects, so he abandons his wife. She searches and finally finds him on a plantation in a Louisiana swamp where she discovers that he is turning into an alligator man along with several other victims of the same failed medical treatment. He has hair and wears pants, but the skin on his face and hands and arms is mutating into alligator skin. Interestingly, though, he can still play a classical piano piece very well with his alligator claws. Lon Chaney has a brief role as a drunken alligator-hating Cajun who wears a hook after his hand was bitten off by an alligator.
There are lots of shots of live alligators in the movie, and we see a couple of scenes of men catching them. And, of course, a real live Alligator Person is shown at the end. That's not just a guy in a silly rubber suit. No way.
