In 1978, holidaymakers including Robert "Popeye" Lespinasse (Thierry Lhermitte), Jérôme Tarayre (Christian Clavier), and Bernard Morin (Gérard Jugnot) arrive at a Club Med camp in Assinie, Côte d'Ivoire, seeking to forget their problems. The group participates in organized activities and casual encounters, including extramarital affairs and flirtations. A tragic incident involving a stingray sting forces them to re-evaluate their relationships, leading to changes among the group members.
