Space Station One is sent out of control by a cosmic explosion at the edge of the solar system and becomes lost in space. Tim and Tam investigate a nearby planet in a spacemobile while June and Craig repair the station. But the teens are captured by lizard women. A small alien helps them escape and they take him back to his planet of Syltron. The little people help the space station avoid burning up in a sun with their space fleet, and Tim and Tam drive off a giant space insect attacking Syltron.
