An airliner makes a forced landing at night in the desert. The passengers and crew take refuge in a nearby deserted house. Soon some of the passengers are found murdered, and one of the passengers reveals himself to be a detective who was guarding one of the murdered passengers, who was carrying a bag of diamonds--which is now missing. The detective must find out which of the passengers is the killer.
