Its an ordinary day at Sunnyview Elementary for Eugene, Charlie, and Sally. At least until the classroom door opens and a teacher who isnt Ms. Beasley walks in. And hes not just any teacherhes a sinister substitute teacher! But where is Ms. Beasley?
Eugene can only think of one explanation: the evil substitute must have captured and hidden her someplace no one will find her well, no one except the Sunnyview Superhero Squad, of course! With time running out and their favorite teacher on the line, its up to Captain Awesome and his crew to rescue Ms. Beasley!
