Gore-filled French zombie horror. When detective Mathias Rivoallan is murdered by a gang led by the Nigerian Markudi (Eriq Ebouaney), four of Rivoallan's colleagues (Aurelien Recoing, Claude Perron, Jean-Pierre Martins and Antoine Oppenheim) hatch a plan to avenge their friend's death by executing Markudi and his henchmen in an abandoned building. However, it soon turns out that the gangsters are the least of their worries when the building comes under siege from an army of flesh-hungry zombies, and the two sides must quickly bury their differences and band together to fight the bloodthirsty undead.
