This isn't an American International drive-in filler but instead a Russian science fiction effort, originally titled Otroki Vo Vselennoi. The protagonists are a group of clean-cut futuristic Soviet teens, who travel to a distant planet within the constellation Cassiopeia. They discover that the planet was enslaved by robots and they must help a handful of surviving humans to get rid of this totalitarian set-up. Teenagers in Space is a sequel to an earlier sci-fier, Moscow-Cassiopeia.
