Will Strong is about to start his first term at Sky High, a school for Superheroes. Great things are expected of Will because he is the son of not one but TWO superheroes, the Commander, who is superstrong, and Jetgirl, who can fly (their cover is selling real estate, they get almost as excited about selling a house as about saving the world). Unfortunately, will's superpowers have not developed yet, and he is too embarrassed to tell anyone. So on his arrival at Sky High, he finds that all the students have to demonstrate their powers to the Coach, who decides whether they will take the Superhero course, or the Sidekick one. Will ends up in the Sidekick class. So does his best friend, a very pretty girl with am amazing talent which she refuses to demonstrate because she disapproves of the Superhero/sidekick division. Will also finds he has trouble with the school badboy, whose father was put in jail by Will's father, and who consequently hates Will.
When Will's superpowers eventually develop he is promoted out of the Sidekick class, and starts dating the glamorous school president. His best friend is not happy about this as she has a crush on Will herself (though he of course hasn't noticed). However, when danger threatens Sky High, it turns out to be the despsed Sidekicks who have just the right powers to save the day, along with Will and the badboy who find they are obliged to settle their differences and work together.
This is a film that everyone should enjoy. The kids will love the exciting story and spectacular special effects, and there is plenty of humour that will appeal to adults.
