La Grand-Messe plot
Ten days before the Tour de France crosses the Col d'Izoard, the first supporters settle with their camper on the berm of the climb. As they move very slowly towards the moment when their heroes flash by, ordinary life goes on as usual. The directorial duo Rosier and Fortunat-Rossi follow the residents of four motorhomes 'on the left of the road four kilometers from the top', as they call the people who stay at home, so that they know where and when to pay attention during the live broadcast. They play card games, sing, eat and drink together and tell each other their life stories.
