In this adventure, a commercial plane crashes in a remote South American jungle. All but one of the passengers survive. Unfortunately, he was the sheriff in charge of taking a dangerous criminal to the executioner. During the excitement of the crash, the prisoner killed the lawman. Among the other survivors is a famous singer, a washed-up funnyman, a mentally ill teacher, and a writer looking for his sister who married a missionary and is now living in the jungle. Amazingly, she is rumored to live fairly close to the crash sight. The survivors manage to make it to the isolated village where she resides. There the writer learns that his sister's husband has gone insane and that she is dead. The megalomaniacal missionary now believes himself king of the natives and is preparing the author and a few others to become human sacrifices when a neighboring tribe intervenes and saves them. The amiable natives then take the survivors back to the wreckage where navy rescue helicopters are preparing to land.
