An expedition to the moon encounters a race of "Cat-Women", the last eight survivors of a 2-million-year-old civilization, deep within a cave where they have managed to maintain the remnants of a breathable atmosphere that once covered the Moon. The remaining air will soon be gone, and they must escape if they are to survive. They plan to steal the expedition's spaceship and migrate to Earth.
When the evil alien Zanon comes to enslave earth, all hope seems lost. The Earth's resident superheroes, the Spacewomen, are powerless to stop him. They must enlist the help of a young boy who has a special connection with the giant turtle Gamera. The Friend of All Children then battles Gyaos (a huge flying vampiric bat/pterosaur), Zigra (an alien shark), Viras (a space squid), Jiger (a giant phehistoric dinosaur), Guiron (a knife-headed extraterrestrial demon beast) and finally Barugon (a enormous lizard whose tongue sprays a freezing liquid that can freeze things solid and a massive back which emits a powerful rainbow energy ray that can melt or dissolve any hard solids). Gamera self-destructs in the end to destroy Zanon once and for all and protect the earth.
On a desolate planet, a team of 12 Xeno project scientists are conducting an archaeological excavation of the ruins of an ancient civilisation. Shortly after an underground tomb network is found to contain crystals and wall inscriptions, photographer Dean White (Dominic Jephcott) is engulfed in a rock blast and left incapacitated. Deciphering the alien language in the caves, xenolinguist Mitch (Trevor Thomas) theorises that the civilisation was built on the concept of dualism: the planet orbits a binary star, and a pair of twins seems to have ruled the race that once inhabited it. Medical assistant Sharon (Heather Wright) discovers that an energy field surrounds the crystals, which causes her to deduce that a "chemical intelligence" controlled life on the planet.
A group of highly qualified single men, including Dr. Richard Stanton (William Lundigan) and Dr. Jerry Lockwood (Richard Carlson), are recruited for a top secret project. They undergo a series of rigorous physical and psychological tests, during which Stanton becomes attracted to the beautiful Dr. Jane Flynn (Martha Hyer), one of the scientists testing the candidates. After most of the candidates have been eliminated from consideration, the four remaining are told about the purpose of the project.
A small ship travels to a rotating space station. Aboard the station, a group of starfish-like beings discuss how to warn humans of an impending disaster, deciding on contacting Japanese scientist Dr. Kumara. Meanwhile, flying saucers are spotted over the skies of Tokyo, baffling scientists. A journalist tries to get a statement from Dr. Kumara about the sightings, but Kumara replies that there is not enough evidence to formulate a hypothesis. At an observatory, Professor Isobe spots an object in his telescope apparently releasing smaller objects.
The Stooges tell their infant sons (also the Stooges) a story about the time they blasted to outer space. In this story, the Stooges are assistants to Professor Jones (Emil Sitka) who travel to the planet Sunev (Venus spelled backwards). The planet's leader, the Grand Slitz of Sunev (Gene Roth) greets them cordially enough, but it soon becomes apparent that he has plans to bring prehistoric men to life and take over the planet Earth. No sooner does Professor Jones catch onto the Grand Slitz's plan does he end up being tied up.

Two escaped convicts, Gary (Tommy Cook) and Lon (Gary Clarke), are discovered hiding aboard a rocket by scientist Dirk Green (Michael Whalen), who then forces them to pilot the spaceship to the Moon. Dirk, who is secretly a Moon man, wants to return home.
A Soviet scientific expedition is being prepared as the world's first mission to planet Mars. Their space ship Homeland has been built at a space station, where the expedition awaits the command to start.
Le journaliste Ray Peterson rejoint une des stations spatiales qui gravite autour de la Terre, à la recherche d'une histoire sensationnelle. A la suite de la mort subite de son pilote, le vaisseau spatial - ALFA 2 - sous pilotage automatique est maintenant incontrôlable. En perdition, il navigue à une course effrénée autour du système solaire, et lors de sa prochaine révolution, il s'approchera très prêt de la Terre à une distance de 3500 miles. Il doit être stoppé à tout prix, car à l'intérieur du vaisseau, un champ Pholonique au rayon d'action de 5000 miles développant une superficie de chaleur incalculable, répandra avec lui mort et destruction...
The film begins with footsteps leading to a pond. The camera continually moves upwards to show the flight of butterflies, birds, and a progression of historical aircraft ending with a rocketship travelling through space and landing on the moon.
The film is set in 1980s Moscow. Standing right in the city centre on Kalinin Prospekt, a barefoot man dressed in a tattered coat appeals to anyone with a strange request: "Tell me the number of your planet in the tenture? Or least the number of your galaxy in the spiral?". Random passers-by, two Soviet citizens previously unknown to each other ("Uncle Vova", a gruff construction foreman from Moscow, Vladimir Mashkov, and a "Violinist", a student from Georgia, Gedevan Aleksidze), start a conversation with him, during which the stranger shows them an alien teleportation device – "traveller". The foreman Mashkov holds out his hand to the device and, despite the stranger's warnings, presses a random button. Suddenly Uncle Vova and the violinist find themselves alone on the desert planet "Pluke" in the "Kin-dza-dza" galaxy. From that point on, the movie describes their long quest to find a way back home.
