Marshall for a Week.When Galaxy High experiences a budget deficit, Principal Kirkpatrick comes up with a solution to get the funds necessary to keep the school up and running: offer a "Week At Galaxy High" to the highest bidder. And the winner is… Thurston Styles III – an incredibly enthusiastic, ultra rich guy who wants to experience every aspect of being a space marshal! From the moment Thurston arrives at GH, however, he’s a whirlwind of disaster – and Josh, Yoko and Brett, who’ve been placed in charge of him, can’t wait to get rid of him. Matters only get worse when they take Thurston on a mission. He likes it so much that he decides that he never wants it to end. After all, this is his big chance to become a space marshal (you see, when he applied to Galaxy High, he didn’t pass the psychological exam). And so, he takes over the ship, forcing the team to go on an extremely dangerous mission – one that will surely end in disaster! Can the gang stop him before it’s too late? In a b-story, Yoko gets a really scathing review of her most recent performance in the GH digital newspaper… and is determined to find out who wrote it! Turns out, her worst critic is actually a computer.
