Aboard a private plane, pilot Hank Brady pulls a gun on his lone passenger, Franz Kovaz, after putting the instruments on automatic pilot. Waiting at Tangier airport is another American pilot, Gil Walker, his French girlfriend Nicki and her companion Danzer, a woman named Susan Lane, and a police lieutenant, Luzon. The plane passes over the airport, then crashes and bursts into flame.

Captured by police while investigating the wreck, Gil and Susan are taken in to Luzon's superior, Col. Wier, for questioning. It is revealed that Gil had known Hank during the war and Susan had been engaged to him.

Suspicious characters follow them, led by Danzer, who forces his way into their car. It turns out Kovaz was carrying forged documents worth a great deal of money. Gil, Susan and Nicki are held by Danzer's men, but they are found by the police, led by Luzon, who is shot and killed. Gil escapes.

Gil ends up on the run, suspected of murder, and not sure whom to trust. The plot thickens when both Hank and Kovaz turn up, having parachuted to safety from the plane. In a final confrontation, Hank and Susan are both revealed to be US government agents, working undercover. Hank is killed. During a gunfight, most of the gang, and Nicki, are killed.
