When Galaxy High receives distress signals from various planets in the universe, Principal K sends several teams out to investigate. When they arrive at their various destinations, they uncover that the planets are not only abandoned, but completely dried out -- what were once fertile, colorful worlds are now dusty and desolate. But before the teams can investigate further, Kirkpatrick informs them that yet another planet has sent out a distress call. Josh's team springs into action, heading toward the planet in their Hornet. When they arrive, they are shocked to discover the planet being drained of its water supply by a large alien ship!
