Louis works for a dry cleaner in the Parisian suburbs. He lives in a council flat with his wife, Chantal, who works as a cashier in a local supermarket. Their relationship is tumultuous and lackluster; Louis longs to escape his humdrum existence. He wants to find a truck to drive to Lebanon. To carry out his plan, he commits a robbery at the supermarket where his wife Chantal works. His plan goes wrong when he fatally wounds a store employee and a security guard. He manages to leave the supermarket unharmed, his loot in his pockets. However, one person witnessed the gruesome scene: Lucie, another cashier. Why does this woman, who seems to have all the evidence to incriminate him, remain silent? Louis is determined to get to know Lucie to better understand the intentions of this mysterious man.

When a neo-Nazi group of terrorists is set to blow a pop concert off the face of the earth because it is an anti-racist benefit, they are faced with the intrepid Jean-Pierre Mougin, a macho sports reporter with zero tolerance for Nazi hate crimes. Going along with Mougin to stop the bombing is Lyza, whose brother was killed by this group of fascists, and so she is ardently seeking revenge. After Mougin gets his hands on a videotape that reveals the plot to blow up the concert and its audience, he and Lyza join forces. As the fuse gets shorter and shorter, Mougin is also joined by sympathetic street gangs. Thus reinforced, he faces his opposition (including crooked cops) in increasingly more desperate attempts to stop Murmeau, the leader of the Nazi gang, from carrying out his terrorist objective.
