This is a horror movie with some pretty nasty violence, but for me the most horrible thing in the movie are the terrible living conditions we see for the animals in a zoo in 1933. There's also too much forced comedy, but there's also a grisly scene with some alligators.

Lionel Atwill is nice and creepy as Eric Gorman, a rich guy who comes back from India with a lot of wild animals for a zoo. (Never mind that he's bringing chimpanzees and a "green mamba" and other animals that are only found in Africa.) He is very jealous of his wife Evelyn, played by the beautiful Kathleen Burke, so when he finds out that Evelyn is planning to leave with another man, Gorman kills him with a severed snake head device full of mamba venom, and blames it on an escaped mamba, shutting down the zoo. When Evelyn finds the snake head device, she goes to the zoo to tell Dr. Woodford (Randolph Scott) the zoo's toxicologist, but Eric stops her and throws her into a pond full of alligators that eat her alive. The next day some boys fish out part of her dress, and that's how her death is discovered. Don't worry, wife-killer Gorman gets what's coming to him in the end.
