Alice Tomaso gets out of jail, and goes looking for Léo and Julien, one of whom, it appears, is her father. On the way, she steals the wrong car - one belonging to the Russian mafia, and arrives at her destination with a gang of thugs out looking for her and the car.
In spite of their total inexperience, three suburban lascars launch themselves into close protection. Thanks to a "mythical plan", they are assigned to protect Marie Van Verten: a capricious and whimsical young woman, heiress of the biggest fortune in Belgium... And incidentally, a target for over-trained killers! Will our heroes' sense of improvisation be enough to get them out of trouble?
