Split – Plot Summary & Ending Explained

Split, directed by M. Night Shyamalan, is a psychological horror-thriller that weaves a tale of fractured identities and the complexities of the human mind. The narrative revolves around Kevin Wendell Crumb (James McAvoy), a man with Dissociative Identity Disorder (DID) harboring 23 distinct personalities. As the film unfolds, three teenage girls – Casey Cooke (Anya Taylor-Joy), Claire Benoit (Haley Lu Richardson), and Marcia (Jessica Sula) – find themselves abducted by Kevin.

The captives soon discover that Kevin’s personalities include the menacing Patricia, the obsessive-compulsive Dennis, the 9-year-old Hedwig, and the controlling Miss Patricia. As the girls attempt to navigate their captivity, they unravel the mysteries of Kevin’s mind, each personality holding a key to the puzzle.

The overarching threat emerges with the emergence of the mysterious and ominous 24th personality known as “The Beast.” The Beast is described as a superhuman entity with supernatural abilities, driven by a belief in the impurity of those who have not suffered.

The tension heightens as The Beast is unleashed, leading to a chilling climax that sets the stage for the broader narrative within Shyamalan’s cinematic universe.


The strength of Split lies in the multifaceted portrayal of Kevin Wendell Crumb and his various personalities.

  • Kevin Wendell Crumb (James McAvoy): McAvoy delivers an extraordinary performance, seamlessly transitioning between the numerous personalities within Kevin. From the vulnerable Barry to the intimidating Patricia, each persona is distinctly characterized, showcasing McAvoy’s versatility as an actor.
  • Casey Cooke (Anya Taylor-Joy): Taylor-Joy’s portrayal of Casey brings depth to the narrative. As a character with her own traumatic past, Casey’s ability to understand and navigate Kevin’s personalities becomes a central element in the story.
  • Dennis, Patricia, Hedwig, and The Beast: These distinct personalities, each with its own quirks and motivations, contribute to the suspense and unpredictability of the film. The seamless transitions between Dennis’s stern demeanor, Patricia’s controlled sophistication, and Hedwig’s childlike innocence add layers to Kevin’s character.

The interactions between Kevin’s personalities and the three abducted girls create a tense atmosphere, with each revelation about Kevin’s condition deepening the psychological complexity of the narrative.
