22 year-old Sébastien (Georges Babluani) leads an impoverished life constantly struggling to support his immigrant family. While repairing the roof of a neighbor's house, he overhears a conversation about a forthcoming package which promised to make the household rich. Sensing the opportunity of a lifetime, Sébastien intercepts the package which contains a series of veiled instructions. Following the cryptic clues, he assumes a false identity and manages to slip through the grasp of the encroaching police as he ventures deeper towards the unknown. The closer he gets to his destination, the less he understands. Ultimately, he comes face to face with a disreputable ring of clandestine gamblers placing bets on a depraved game of chance where the spoils are unimaginable millions, and the losses are counted in lives.
