In a small coastal village in France, the tranquil pace of life at the gendarmerie is shaken by the arrival of extraterrestrials. The officer in charge of maintaining order, the clumsy yet well-meaning gendarme Cruchot, played by Louis de Funès, faces one of his greatest adventures: combating a threat that transcends his world. When the aliens, equipped with their peculiar suits and supernatural abilities, land on the beach, the entire village is thrown into widespread astonishment and panic.
Cruchot, with his characteristic explosive and scatterbrained nature, tries to establish a plan to manage the curiosity and fear of the locals, but the situations quickly spiral out of control. The communication between gendarmes and aliens becomes a true comedic challenge, filled with hilarious misunderstandings. The extraterrestrials, in an attempt to study humans, create absurd situations that jeopardize Cruchot's authority and that of his squad.
