In the idyllic and glamorous French Riviera, the strict and somewhat clumsy gendarme Cruchot is transferred to the tranquil town of Saint-Tropez. His mission: to maintain order in this paradise where the sun shines and the parties never end. However, Cruchot is unprepared for the laid-back lifestyle of the vacationers, nor for the mischief of the tourists who fill the beaches with fun and chaos.
Soon, he finds himself caught in a whirlwind of comedic situations as he attempts to enforce the law in a world that seems to take nothing seriously. With his unyielding sense of duty, Cruchot faces a series of hilarious misunderstandings, such as mistaking a movie star for a criminal because of her revealing outfit. As he deals with a gang of criminals planning to ruin everyone's holiday, things become even more complicated when he falls in love with a charming woman who also knows how to flaunt her independence.
With a cast of eccentric characters and comedic scenes that include ridiculous chases and absurd mishaps, the gendarme is forced to balance his commitment to the law with his desire to enjoy the sun and fun. The movie is a delightful satire about the clash between duty and pleasure, where laughter becomes the best remedy for chaos. As summer comes to an end, Cruchot will discover that keeping the peace in such a vibrant place is no easy task, but likely the most enjoyable one.
