Pierre Blum, 40, is a writer who had his time of glory in the early 2000s. One evening, on a casino terrace, he meets Joseph Paskin. This mysterious man, charismatic and manipulative, is influential in the world of politics and persuades Pierre to take on a strange mission that takes him back to a past he’d prefer to forget, and puts his life in danger. In the middle of all this, Pierre falls in love with Laura, a young extreme-left activist. But in this world of subterfuge, who can really be trusted?
