ToggleDetailed Summary
The Abduction
The film begins with three teenage girls being kidnapped in broad daylight by a man who appears calm, polite, and disturbingly controlled. This man is Kevin Wendell Crumb, portrayed by James McAvoy, who suffers from Dissociative Identity Disorder (DID). At first, his behavior seems strange but manageable.
Meeting the Personalities
As the girls are imprisoned in an underground facility, they begin to encounter Kevin’s different identities. Some are harmless, even kind. Others are deeply unsettling. Among the most notable are:
- Dennis, obsessive and controlling
- Patricia, strict and motherly
- Hedwig, a lonely nine-year-old boy
The film carefully reveals these personalities, creating tension without immediately showing violence.
Casey’s Trauma and Survival Instinct
One of the captives, Casey Cooke, stands apart. Quiet, observant, and emotionally guarded, she has a traumatic past of her own. Her ability to read Kevin’s personalities and adapt becomes her key to survival. This parallel between trauma and strength is one of the film’s emotional cores.
The Arrival of “The Beast”
Kevin’s therapist, Dr. Fletcher, believes Kevin has 23 personalities—but rumors of a 24th begin to surface. This identity, “The Beast,” is said to possess superhuman strength, resilience, and a god-like sense of purpose. As the personalities lose control, The Beast begins to emerge.
Movie Ending
The final act reveals The Beast in full. Kevin undergoes a horrifying physical transformation, displaying inhuman strength, agility, and pain resistance. He kills two of the captive girls without hesitation, believing that those who have not suffered are “impure.”
When The Beast confronts Casey, something unexpected happens. He notices scars on her body—evidence of past abuse. Instead of killing her, he sees her as “pure” because she has endured suffering. He spares her life and leaves her alive in the facility.
Meanwhile, Dr. Fletcher is murdered after realizing that The Beast is real, proving her theory that the mind can alter the body beyond known limits.
The film closes with Casey being rescued and hospitalized, emotionally shattered but alive.
Then comes the twist.
In a diner, a TV report discusses Kevin’s crimes, comparing him to a mysterious criminal from years ago. A customer responds, “What was that guy’s name? Mr. Glass?” The camera cuts to Bruce Willis as David Dunn, confirming that Split is secretly set in the same universe as Unbreakable (2000).
This revelation recontextualizes the entire film, turning it into a stealth sequel and setting up Glass (2019).
Are There Post-Credits Scenes?
There is no traditional post-credits scene, but the final diner scene functions as a universe-connecting stinger. Viewers familiar with Unbreakable instantly recognize its importance.
