Provincial crook José plans to rob an armoured car but the heist goes wrong. He and his two mates hide in a bunker measuring all but 13 square meters. Soon, every movement triggers hysterical paranoia. Any thought of escape seems pointless. Their friendship is on the brink of collapse. Unusual for French films, Grossman’s directing debut is reminiscent of his idols Coppola, De Palma and Spielberg.
