A group of brash hard young men from Marseille moves to Pigalle, Paris, and starts knocking over jewelry shops, gas stations, road houses and bistros - wearing wraparound sunglasses and brandishing Luger pistols and Sten guns, bistros in their efforts to conquer part of the violent and brutal criminal underworld until then «owned» by the established criminal organization. They spend time torturing, killing and intimidating the old generation of gangsters and their molls, until they either pay up or die.
