Secret défense (2008)

A terrorist group is identified in Damascus by DGSE agents. Alex (Gérard Lanvin), a DGSE team leader, recruits Diane (Vahina Giocante), an Oriental languages student and his son’s girlfriend, as a new agent. She undergoes training to blend into crowds and gather information. At the same time, in Lille, Pierre (Nicolas Duvauchelle), a petty criminal, is sent to prison, where he befriends a jihadist network that sends him to train at a camp in Afghanistan to carry out attacks. Learning that the weakness of the cell’s leader, Al Barad (Simon Abkarian), who is suspected of planning attacks, is his habit of associating with women, Alex sends Diane to Beirut, Lebanon, under the identity of Delphine Boileau, a wine merchant. There, she discovers that something is going to happen on [date missing]. Unmasked, she is taken to Paris by Al-Barad, who wants to witness the attack he is preparing. At the same time, Pierre, who goes by Aziz, returns to Paris with toxic gas to carry out an attack in the subway. Al-Barad is arrested, but Diane searches for the briefcase containing the toxic gas. She spots it and follows the van, where Pierre is wearing an explosive belt. He takes Line 4 of the subway and prepares to blow himself up. Diane manages to stop him and has security arrest him. She then learns that her lover was not Alex’s son, but was actually a DGSE recruiter who manipulated her so that Alex would meet her. During Al Barad’s interrogation, we also learn that Diane/Lisa’s former client (Saïd Amadis) is, in fact, also a DGSE agent, sent by Alex as part of the real team operating behind Diane, who, unbeknownst to her, had been sent as a smokescreen. Alex then pays his respects before the memorial plaque for agents who died on duty.
