Völlig überraschend erhalten die Schüler der Galaxy High die Nachricht, dass Lehrer Fitch in den Ruhestand geht. Sein Nachfolger, ein Alien namens 6025 A-46, ist bei den Schülern aufgrund seiner relaxten Art und seiner lockeren Sprüche zunächst sehr beliebt. Allein Brett findet ihn seltsam und schließt sich nicht der allgemeinen Begeisterung an. Aus gutem Grund: bald stellt sich heraus, dass 6025 mit Hilfe eines Plasmoboters, den er zusammen mit einigen Schülern im Unterricht gebaut hat, die Leitung der Schule an sich reißen will …
When Principal Kirkpatrick informs the students that Mr. Fitch has retired, they cheer. But when he explains that Galaxy High will be getting a new teacher to replace him, they respond with typical teenage moans and groans. But their attitudes quickly change when they meet Mr. 6025-A46 – a dynamic, charismatic, fun-at-all-cost alien teacher! With his far-out teaching style (he doesn’t believe in homework and gives out gold star lapel pins instead of grades), and his unorthodox curriculum (instructing the students in a variety of cool infiltration and attack techniques), Mr. 6025-A46 soon becomes the most popular teacher on campus, winning the hearts and minds of all the students… with the exception of Brett, that is. Though Josh and Yoko try to convince him otherwise, Brett is certain there’s something not quite right about this guy. After doing some snooping, Brett confirms his suspicions… Mr. 6025-A46 is actually an evil alien who escaped from the Galaxy High containment facility long ago. But before Brett can warn the others, the imposter teacher activates the hidden mind-control frequency in the students’ lapel pins, causing them to turn from space marshals into his personal army of mutineers. With the Galaxy High students now under his control, he leads an all out assault to take over the school. It’s up to the faculty and Brett (who never earned his gold star), to stop the rogue students and their evil leader, and return order to the school before it’s too late! In a b-story, the students are surprised to hear that Mr. Fitch has retired. But ultimately, they discover he’s really been kidnapped by their new teacher and are thrilled to get him back in the end.
