T. F. Stockwell (Herbert Rawlinson) steals the money and jewelry contents of safe deposit boxes of the Cairo bank in which he works. After fleeing south in a private plane with his young daughter Doreen (Jackie Newfield, daughter of the director) and the pilot, they're brought down in the jungle during a storm. The three survive the crash but Stockwell murders the pilot when he sees the stolen loot. Whilst exploring the surroundings, Doreen finds a gorilla (Ray Corrigan) wounded and left for dead by members of a safari.
