Bazil (Dany Boon) has been a victim of weapons manufacturers his entire life. His father was killed by a land mine, and Bazil lost his job after he was shot by an errant bullet -- which is still lodged in his skull. Now Bazil lives on the streets of Paris, where he encounters Slammer (Jean-Pierre Marielle). Slammer takes him under his wing, introducing him to other outcasts. With the help of his new entourage, Bazil devises a plan to exact revenge on the companies that took so much from him.
