 Originally released in 3-D, the film begins when a pilotless plane crashes at the Tangier airport. Those awaiting the plane include Gil Walker (Jack Palance), a sometime dabbler in black-market operations and an unjustified winner of a Congressional Medal of Honor; Susan (Joan Fontaine), an Americal girl engaged to the missing pilot; and Nicole (Corinne Calvet), a French girl whose affections seem to be evenly divided between Walker and various other Tangier underworld characters. The plane was supposed to be bringing in $3,000,000 to finance the purchase, by an Iron Curtain agent, of war planes from a Tangier black-market operator. Susan enlists the aid of Walker to find the missing pilot and the money, which she knows to be safely hidden 75 miles south of Tangier. The chase is on with Susan and Walker pursued by the black-market racketeers who, in turn, are trailed by the police.
