In a world where comic book mythology bleeds into a stark reality, three men with extraordinary abilities find themselves confined within a mental institution under the watchful eye of a mysterious psychiatrist. M. Night Shyamalan concludes his grounded superhero trilogy as security guard David Dunn (Bruce Willis), the unbreakable vigilante from Unbreakable, uses his supernatural strength to hunt the monstrous Kevin Wendell Crumb (James McAvoy), the fractured antagonist from Split. Their fated confrontation is orchestrated by the brilliant and manipulative Elijah Price (Samuel L. Jackson), the mastermind known as Mr. Glass, who believes their existence proves humanity is on the verge of an evolutionary leap. As Dr. Ellie Staple (Sarah Paulson) works to convince them their powers are merely delusions, a tense psychological battle erupts, forcing each man to confront the truth of their own legend. This cerebral thriller weaves a suspenseful tapestry of identity, belief, and the fragile line between hero and villain, building towards a revelation that will challenge everything the world thinks it knows.
