Paris, France, early 19th century. The legendary convict François Vidocq lives in disguise trying to escape from a tragic past that torments him. When, after an unfortunate event, he crosses paths with the police chief, he makes a bold decision that will turn the ruthless mastermind of the Parisian underworld against him.

Outwardly a chilling portrait of the aimless lives of unemployed inner city youths living on society's fringe, the underlying message of this volatile drama seems to call for violence to rectify social injustices. The film centers on two teenaged gangs who basically terrorize their neighborhoods with their anarchic behavior. There are few limits to their unpleasant philosophy of "desire equals acquisition." The loosely structured tale reaches its climax at a concert where the two rival groups collide.
