Prelude to a Storm

S11, E1: Three young extreme sports fans, surfer Tori, skateboarder Shane, and motocrosser Dustin, spend their afternoons together at the Wind Ninja Academy, where the future stealth protectors of the Earth are trained in secret. Though, they're considered to be the three least dedicated students, the trio's potiental and good nature comes to an advantage, when they run late for class one afternoon. It just so happens, that day, Lothor, a banished evil ninja, comes back to the planet, and conquers every Ninja Academy with his hoard of Evil Alien Ninjas! With their Sensei trapped in the form of a Guinea Pig, and his grumpy and embittered tech-wizard son Cam designing the weaponry to combat the villains, the three become the Wind Ninja Rangers. Can they manage to defeat the Blue Face monster in their first battle?
