Smalltown confectioner Lespinasse, hopeful of being reelected as chief councillor, is opposed by Darcepoil, the local druggist. Darcepoil arranges for the incumbent's defeat by having Pantaflon, a nightclub singer, lure him to the nudist camp on the Isle of Levant, where Lespinasse is photographed surrounded by half-naked women. At home, he is berated by his wife and thrown out of office; but he returns to Levant with the penitent Pantaflon and is welcomed by the nudists and voted camp president. His forgiving wife follows him and herself becomes a nudist.
