A second-class horror movie has to be shown at Cannes Film Festival, but, before each screening, the projectionist is killed by a mysterious fellow, with hammer and sickle, just as it happens in the film to be shown.

Clara (Karin Viard) is a stripper with a high-strung, jealous boyfriend with the curious name of Loockeed (Antoine Chappey). The couple are friends with the even-temperred, almost saintly Max (Gerald Laroche), an auto mechanic. The three of them set out from their home in the north to journey to the Alpine mountains near Switzerland and Italy, where they will help a fourth friend take care of his pleasure boat business at Lake Annecy while he is in military service. As the trio attempt to establish some sort of equilibrium in their new lives, Max must constantly deal with Loockeed's testy, jealous barbs. Despite this, the three of them remain friends.
