You want a fucking synopsis or something? Have you not seen the movie?

It’s the movie where a kid struggles to fit in with the genetically superior upper class, gets sorted into lower class at school, but then later he overcomes the weakness of the lower people and joins his proper place in aforementioned superior class.

Will’s Parents are genetically superior superheroes with indestructibility, super strength, and the mom can fly. Will has no such power and has been lying to his parents about his lack of abilities, and as such is forced to attend a school for mutant children. At the school, they sort people into two separate social groups: Heroes and Sidekicks, based on characteristics they were born with. Will is sorted into sidekick because he has no powers and has to come clean to his parents. He learns that all sidekicks must support a hero, not allowed to perform any actions on their own. The sidekicks are treated as a lesser class of people with vastly inferior resources and amenities. Will’s parents are very upset and consider momentarily to dump him in a vat of radioactive material. Will, of course, then magically develops the superpowers of his parents. The sidekicks are the only ones not caught in a major disaster and they finally get their time to save the day: by supporting Will because they can’t do anything on their own.

Moral of the story: You’re either born superior or inferior, regardless of your personality, and there is nothing you can do to change it.
