The Wind Ninja Academy is a prestigious institution for aspiring ninja. Unfortunately, Shane, Tori, and Waldo seem to be washouts – until the evil ninja master Lothor captures all the other students and turns their sensei, Kanoi Watanabe, into a guinea pig. Watanabe turns the three remaining students into Wind Power Rangers by giving them Wind Morphers. They join the Thunder Rangers to fight Lothor and his evil minions.
The Rangers defeat all of Lothor's minions – but unfortunately, in the process they overload the Abyss of Evil (to which they were all sent upon their demise). Along with Lothor and his henchmen, the Rangers’ powers end up sealed in the abyss. The sensei is restored to human form. Now returned to their normal lives, the Rangers become teachers at the Wind Ninja Academy.
