Marc, an insurance agent from the provinces, mediocre and very uptight, makes contact with the Mob in order to eliminate his wife, an unbearable castrating boss of a woman. An impromptu and improbable driver during a pathetic jewelry store heist, Marc is taken under Toulouse's wing. A second-rate robber, Toulouse acts less through compassion than through contempt, but he nevertheless shows Marc the ropes through several experiences on the ground. For Marc, this series of encounters and adventures turns out to be a revelation. This journey of nocturnal initiation will allow him to discover his inner killer... still uptight and mediocre, but - at least for now - dangerous!
