At the Tangier airport, a group of people await the arrival of a mysterious plane from behind the Iron Curtain. The reception committee includes Susan, an American; Gil Walker, a free-booting pilot; Danzer, a black market operator; and Danzer's girlfriend, Nicki. The plane crashes and burns. No survivors are found, nor are any corpses. Soon the search begins for a missing courier worth $3 million.
