The son of the world's two most legendary superheroes prepares to attend Sky High, an elite high school charged with shaping the minds and molding the abilities of tomorrow's superheroes. Unfortunately, the young boy doesn't believe that he has any superpowers and instead of being placed in the "Hero Class," he finds himself relegated to "Sidekick" status. All of this on top of the usual high school trials and tribulations make freshman year almost too much to handle. When an evil villain threatens his family, the young boy finds the superpowers hiding within himself to save the day.
