Hobe Carrington, a pilot and former Army intelligence officer, is tempted by a seductive European countess who cajoles him into flying her and few friends, including the beautiful Catherine Forrest, to a remote resort in the California desert. Hobe doesn't realize that the passengers on this flight are eager to get their hands on a valuable map that shows the location of a huge deposit of Uranium - an essential ingredient in the making of atomic bombs. Just as Carrington gets ready for takeoff, he receives a message of warning from his old Army buddy Bob Donovan who is working on the case for the U.S. State Department. Agent Donovan enlists the pilot's aid in locating the secret map before it gets into the hands of unscrupulous Cold War powers. This greedy and murderous group, however, becomes more desperate and dangerous with each passing day.
