When Josh’s team is sent on a mission to investigate a series of explosive disturbances in outer space that are sending shockwaves throughout Galaxy High, the gang comes across a small planet with two warring sets of alien neighbors on it. Turns out that the explosions are actually coming from the alien inhabitants who have been fighting one another for several millennium. The students immediately intervene, trying to keep the peace, but in no time, Yoko, Brett, Josh and Fluffy are unwittingly being used as pawns in the feud. No matter how hard they try to get the aliens to call a truce, the feud only gets worse. As the fighting escalates, no one realizes that the disturbances have actually started to pull the planet in half – potentially creating a chain reaction that could destroy half the universe. Can the GH team convince the aliens to put their differences aside and work together to save themselves? In a b-story, Brett is convinced he’s allergic to Josh until he finds he's allergic to Fluffy's cleaning pasta. And Yoko becomes arrogant with her knight role to the school play.
