Eustache carries the heavy burden of a difficult past, including a lost childhood. He and his fellow cat burglar and partner, the diminutive Mouche, break into wealthy homes for a living. One day, they make a shocking discovery in the safe they have just cracked: the film negative of a "snuff film," a movie where murders are committed for real, to excite perverts. After this macabre surprise, a trail of death begins to follow the pair.

Written and drawn by prolific European stars Corbeyran and Cecil.
