Foreman Uncle Vova and Georgian student Gedevan accidentally found themselves on a strange desert planet, Plyuk, in the faraway galaxy 'Kin-Dza-Dza'. The planet's inhabitants looked like humans and understood Russian, because they could read people's minds, although their own language was pretty limited. Virtually everything, with a rare exception, was expressed by one word - 'koo'. The planet's entire population was divided into two castes: the superior one - 'chatlians', and the lower one - 'patsaks'. Uncle Vova and Gedevan, who learned they were patsaks, had been trying throughout the film to get back to Earth, in which they finally succeeded, after many an adventure...Georgy Daneliya: 'After my film 'Tears Were Falling', I felt like making something punkish. And I've got an idea - take Stevenson's 'Treasure Island' and place it in outer space: instead of a ship and an island, a rocket and a planet...'  Violinist: - Comrade, there's a man there who says he's an alien. We have to do something! Vladimir Nikolayevich: - Call the ambulance.
