The plot for The Last Stand has been kept essentially secret, but the root of it revolves, like Spider-Man 2, on the ultimate superhero choice: to fly or not to fly.
According to Marvel mythology, mutants are born genetically different from humans. Usually considered freakish social outcasts, the more determined of the species harness their powers -- for good or evil.
In the new film, they are faced with a choice. A genetic breakthrough has brought about a possible cure for mutants. But do they give up on their superpowers, their special abilities?
Is being normal just what they want?
