They are called the "Disappeared." Suddenly, one morning, they leave, taking only the absolute minimum with them or nothing at all. Without a trace, they abandon their partners, wives, children, pets - so many that the police no longer even take missing person reports. They vanish into thin air, just as the entire era dissolves: public buildings and squares are devastated by attacks, garbage is no longer collected, and tear gas hangs in the air. Since the attacks of 2015, France has been in a state of constant unrest. The intelligence service is trying to get to the bottom of the phenomenon. Guillaume Trimbert, 55 years old, an author, former teacher, former husband, and former hero of left-wing demonstrations, has a "threat assessment file," and Agnès Delvaux, just 30 years old, a captain in the intelligence service, is watching him. She breaks into his apartment.
