Fleeing robbers trapped in a worse predator's house
After a Paris jewelry heist goes wrong and his younger brother William is badly wounded, the hardened criminal Raphaël and his accomplices force their way into an isolated country house and take the veterinarian who lives there hostage. It turns out her husband, a gendarme, secretly abducts, confines and tortures young women on the property. The hostage-takers become prisoners of a far more dangerous captor, and the siege turns into a struggle for survival between two kinds of violence.
