When bad boy police officer Ousmane is involved in a car accident, he is mistaken for the assailant by his fellow police officers. The next day, the wife of a business mogul turns up nearby Ousmane's housing project. Ousmane draws connections between the two crimes and believes he is able to solve both crimes. In order to be heard by fellow police officers, Ousmane is forced to team up with visiting Parisian investigator Francois Monge, who has much more departmental clout. Despite coming from and working in very different neighborhoods, the pair find common ground through their policing style, including manhandling suspects and kicking butt.
