In the jungle, the mighty jungle, the Gorilla doesn't sleep tonight. How wonderfully silly. Johnny Weissmuller stars as Jungle Jim, getting himself in a serialisation of a character not a million miles away from the Tarzan role that would define his film career. Plot has Jungle Jim going about his jungle business, hunting in the wild and larking about with his animal pals, when he is suddenly thrust into a mystery involving dubious Gorillas, stolen Nazi treasure and the protection of a couple of babes. Nefarious treasure hunters will stop at nothing to get the treasure, but they hadn't count...
