Bernard, a young, serious publisher of religious books, finds himself embroiled in amusing and eventful adventures with Sophie, a wacky twist dancer. Having lost his own situation, he joins Editions du Soleil thanks to his friend Marcel's manuscript "Comment réussir en amour". Freed of his shyness, he succeeds brilliantly in his career; and having put to good use the teachings of the manuscript, Bernard ends up marrying Sophie. But he soon finds himself confronted by the impetuous young woman's fantasies.
