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.

Un soir sur la plage is relatively interesting; the cast includes highly talented Jean Dessailly, Martine Carol, a cast against type Michel Galabru as the cop.The biggest surprise is sixties starlet Daliah Lavi as a simple-minded nymphomaniac girl who is murdered on the beach. The story is essentially a whodunit: in Martine Carol's house, there are many people (too many people actually) and they all have a reason to get rid of her.
