L'Attentat is a political thriller based largely on a true story (the Ben Barka affair), which recounts how the French government and the American CIA connived to have a socialist in exile murdered before he could return to his homeland and start a revolution. Darien, a French journalist (Jean-Louis Tritignant), lures his friend Sadiel (Gian Maria Volonte) from his safe refuge in Geneva to appear on an American-made TV show. In doing so he is, perhaps unwittingly, setting him up for murder. Captured at the border by the French police, Sadiel is given over to a mysterious general from another country who tortures him to try to find out who his supporters are.
