Laissons Lucie faire ! (2000)

Lucie makes her living selling bathing costumes on the beach at Marseilles. She would like that her ten-year long boyfriend, Lucien, becomes her best friend. But this requires truth. For Lucien, newly made secret agent who has to play a young idler, it is mission impossible. Even more so when a young american beauty will ask him to initiate her into sensual pleasures.
