Psychiatrist Dr. Fletcher’s patient Kevin has evidenced 23 personalities within his fractured mind. But as a more powerful, villainous personality begins to materialize, threatening to dominate the others, Kevin and Dr. Fletcher must grapple with a looming danger that will not only shatter the walls of Kevin’s mind, but also society’s perceptions of reality.
M. Night Shyamalan returns with an original thriller that delves into the mysterious recesses of one man's fractured, gifted mind. 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 the others. Compelled to abduct three teenage girls led by the willful, observant Casey (Anya Taylor-Joy), 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 apart.
