Very few people know that Pierre Marroux (Yves Montand) is the father of the famous terrorist Netchaiev (Vincent Lindon), and that's the way he likes to keep it. His boy is now presumed to be dead, and he has a job to do, protecting the safety of those who pay him. However, the boy has recently returned to Paris with a group on an operation. Netchaiev is tired of being a hunted man and is shopping his potential confession around for the best deal. This puts him at odds with his colleagues past and present, and his life is in great danger. When Pierre learns of the situation, he tries to use his skills to find his son before his killers do. Along the way, he learns that the French government has a very shady deal with the terrorists, and it wants Netchaiev dead, too. This thriller is based on a novel by Jacques Semprun.
