The actions once again take place in the small French town of Saint-Tropez. While driving with one of his gendarmes, Cruchot (Louis de Funes) has to stop in order to fix the car. The gendarme wanders away and sees a flying saucer in a field which then flies away. He tries to tell Cruchot and the rest of the station, but they don't believe him. Shortly after, the same occurs with Cruchot and the chief of the gendarmes. This time it is Cruchot who wanders away and sees the saucer, however the chief does not believe him. Later on, when the same gendarme is doing paperwork in the office, a young man appears in front of him and says that he is a part of an alien expedition which has arrived to Saint-Tropez in order to examine humanity as people from all around the globe go to Saint-Tropez during the summer. The alien demonstrates its shapeshifting ability by transforming into the same gendarme it is talking to. The gendarme runs and tells Cruchot, who doesn't believe him. In the midst of the racket, the chief comes and sends the gendarme away. The chief reveals that he is actually an alien disguised as the chief, and when Cruchot doesn't believe him the alien becomes agitated and uses laser vision to cause damage to Cruchot's room. He relents when a watch on his hand flashes red and drinks something out of a flask. The alien begins coughing and upon hitting it on the back, Cruchot discovers it makes a metallic sound. Later on when the real chief arrives, Cruchot stabs him with a screwdriver thinking that it is the alien. The chief orders Cruchot out, since the supervisor will come in tomorrow to check up on the station. During the check up, Cruchot notices the same watch on the supervisor as on the alien he saw last night and attempts to attack him. The gendarmes hold him back while the alien supervisor flees, and the real supervisor arrive. Cruchot once again stabs the real supervisor thinking he is an alien. He is arrested, but escapes the station.
The film begins on "Friday, April 17" at 4 pm in Venice, California. Huckleberry P. Jones (Gene Cunningham), local pimp, narcotics peddler and slumlord, enters a vacant house that he owns. While stashing heroin in the basement, he stumbles upon a mysterious door and enters it, falling into the Sixth Dimension, from which he promptly escapes. After retrieving the heroin, he sells the house to the Hercules family. On their way to school, Frenchy Hercules (Marie-Pascale Elfman) and her brother Flash (Phil Gordon) have a conversation with Squeezit Henderson (Matthew Bright), who tells them that, while being violently beaten by his mother, he had a vision of his transgender sister René (also played by Bright), who had fallen into the Sixth Dimension through the door in the Hercules' basement. Frenchy returns home to confide in her mother, and decides to take just a "little peek" behind the forbidden door in the basement. After arriving in the Sixth Dimension, she is captured by the perpetually topless Princess, who brings Frenchy to the rulers of the Sixth Dimension, the midget King Fausto (Hervé Villechaize) and his queen, Doris (Susan Tyrrell). When the king falls for Frenchy, Queen Doris orders their frog servant, Bust Rod, to lock her up. In order to make sure that Frenchy is not harmed, King Fausto tells Bust Rod to take Frenchy to Cell 63, where the king keeps his favorite concubines (as well as René). The next day at school, Flash tries to convince Squeezit to help him rescue René and Frenchy. When Squeezit refuses, Flash enlists the help of Gramps instead. In the Sixth Dimension, they speak to an old Jewish man who tells them how to help Frenchy escape, but they soon are captured by Bust Rod. Queen Doris interrogates Flash and Gramps and then lowers them into a large septic tank. She then plots her revenge against Frenchy, relocating all the denizens of Cell 63 to a torture chamber. She leaves the Princess to oversee Frenchy's torture and execution, but when a fuse is blown, the torture is put on hold and the prisoners from cell 63 are relocated to keep the King from finding them.
