After pursuing Kevin Wendell Crumb and the multiple identities that reside within, David Dunn finds himself locked in a mental hospital alongside his archenemy, Elijah Price. The trio must now contend with a psychiatrist, who is out to prove they do not actually possess superhuman abilities.

Though Kevin (James McAvoy) has evidenced 23 personalities to his trusted psychiatrist, Dr. Fletcher (Betty Buckley), there remains one still submerged who is set to materialize and dominate all of the others. Compelled to abduct three teenage girls led by the willful, observant Casey, Kevin reaches a war for survival among all of those contained within him -- as well as everyone around him -- as the walls between his compartments shatter.
