A young journalist uncovers an assassination disguised as a suicide, linked to an American multinational seeking to dominate French industries. Determined to expose the truth, he races against time to gather evidence before more lives—and his own—are at stake.

Vlassov is a Soviet spy who defects in France. He is whisked to the U.S, where Allan Davies takes over the case. After polygraph tests and cross-examinations, Vlassov names several Western European agents who are also spying for the Soviets. Davies wants to take the listed agents into custody; meanwhile, those on the list start dying under mysterious circumstances.
