The police lose track of Sébastien as he follows the instructions and is brought to a secluded house in a forest. At the house, a deadly gambling event is being organized by a powerful criminal. Though Sébastien's contacts immediately recognize that he is not Godon and has no idea what he is getting into, they force him to participate in the game. Thirteen men identified by number must undergo a series of Russian roulette games, arranging themselves into a circle and pointing their revolver at the man in front of them. Spectators place bets on who will survive. Sébastien, as #13, survives the first round and fires his gun only after threatened with death. On the second round, in which two bullets are placed in each gun, Sébastien survives only because the man behind him is killed before he could fire. On the third round, with three bullets in each gun, Sebastien survives along with three other men.
