A returning moon capsule goes off course and lands in Africa where a little-known tribe finds it. Washington sends Matthew Merriwether to recover it—thinking he's an expert on the region—when in fact he's no such thing. However, a foreign power sends Secret Agent Luba to try and acquire the capsule for itself and, when Matthew and Luba reach their destination, they find that the tribe believes the capsule to be sacred and won't give it up.
