Plot synopsis: Jean-Louis is an naive, amiable orphan who spent his life with his elderly and very strict grandfather. Jean-Louis was a 25-year old virgin when a free-spirited young Parisian woman was temporarily stranded in his village after a bus broke down. She left him a changed man, and she also left a match book from a fast food restaurant called Fast Burger. Soon after his grandfather passes away, the innocent rube Jean-Louis hops on his bike and embarks upon a quest to Paris to find this enigmatic woman. But he is not prepared for the size of Paris, and instead ends up working at a Fast Burger outlet himself. Jean-Louis is a simple soul and freely expresses himself without guile. For some reason this endears him to the staff and management; soon he has been promoted into the upper echelons of the company. One day he meets a rather ditzy Metro security guard, Henriette, who is also at sea in the big city. The kindred spirits click and a sweet romance ensues.
