The French Conspiracy (1972)

Sadiel, a Leftist leader in a North African state, takes refuge in Switzerland in the aftermath of a coup. Aware of the threat Sadiel poses, ruthless Colonel Kassar contacts the French security services for help to capture the political activist. Darien, a police informer, is forced to lure Sadiel to Paris, allegedly to make a television piece about the newly independent Western colonies. When Sadiel gets to Paris, he is captured and delivered to his opponents. Disgusted by the way he has been manipulated, Darien tries to turn back the clock, but he doesn't know with whom he's dealing. Loosely based on the true story of Mehdi Ben Barka.
