The Gendarme and the Extra-Terrestrials

Cruchot (Louis de Funès) must stop the residents of St. Tropez from being threatened by oil-drinking humanoid aliens. The only way to identify the aliens is their constant thirst for oil-products and a metallic sound they make when struck on the back. Chaos ensues as Cruchot tries to save the town, aided by his gendarmes, including Jérôme Gerber (Michel Galabru) and Charles Taupin (Jean-Pierre Rambal), who ultimately help him defeat the aliens.
