Nada is a small leftwing terrorist group made up of six people from very different backgrounds. Diaz, the most militant of the group, plans to kidnap the American ambassador Richard Poindexter, in a bid to draw attention to their cause. One of the group, Treuffais, a timid philosophy teacher, will have no part in this and walks away. His five comrades succeed in spiriting Poindexter away to a remote farmhouse. Unfortunately for them, the police chief who is assigned to the case sees the elimination of the terrorists as having much greater priority than rescuing the ambassador.
