Upset that his fiancee wants to take a break in their relationship, and to reduce his stress levels, Jean-Pierre Savelli, an insurance company employee in Clermont-Ferrand, decides to spend his holiday in an unusual place for him - the Blue Waves campsite, near Arcachon. There he meets eager campers including Patrick Chirac, and begins to act as a single man again. At first put off by Patrick's overtures of friendship, the two become best friends, as Jean-Pierre begins to "loosen up" a bit. Taking a lead from Patrick, Jean-Pierre gradually acquires the same outlook on life and even becomes the new darling of Blue Waves, which makes Patrick jealous. Patrick begins to cause discord in the camp, although the other campers (Jacky, Paulo, Laurette and Sophie) are already ill-humored, all the more so when it is revealed that the "Blue Waves" campsite may be sold to a Spanish group, to be replaced by a luxury hotel.
