Exorcism Gone Wrong (2026) takes the familiar horror trope of demon possession and flips it completely on its head, delivering a supernatural comedy that mixes eerie hauntings with laugh-out-loud absurdity. Instead of stoic priests battling terrifying demons, this film follows a team of deeply flawed, often clueless characters who find themselves hilariously unprepared for the paranormal chaos they unleash.

At the center of the story is Joo-won, played by Lee Min-ho, a once-respected exorcist whose reputation was destroyed after a catastrophic ritual went horribly wrong. Now living with self-doubt and a damaged career, Joo-won wants nothing more than to leave the supernatural world behind.
But fate has other plans. His childhood friend Ji-eun, portrayed by Park Bo-young, pulls him back into the paranormal business with her enthusiastic but questionable psychic abilities. Ji-eun firmly believes she can sense spirits—but her clumsy methods and unpredictable visions often create more problems than solutions.

Their chaotic partnership becomes the heart of the film. While Joo-won tries desperately to maintain professionalism, Ji-eun’s impulsive approach constantly turns serious situations into ridiculous disasters.
Joining them is Min-seok, played by Kim Soo-hyun, a skeptical friend who doesn’t believe in ghosts at all—until he finds himself face-to-face with one. His sarcastic reactions to the supernatural events provide some of the film’s funniest moments.
Meanwhile, Shin Min-a’s Soo-jin brings a more confident presence to the group as a fearless spiritualist who believes she can handle any haunting. Yet even her experience proves useless against the bizarre spirits they encounter.

The main haunting takes place in an old house in the middle of Seoul, which quickly becomes the stage for a series of chaotic exorcism attempts. Each ritual seems to unleash something stranger than the last.
Instead of terrifying demons, the group faces eccentric ghosts with absurd personalities. One spirit refuses to leave until someone performs karaoke with it, while another ghost spends its time offering awkward romantic advice to the living.
These unusual hauntings transform what should be terrifying exorcisms into surreal comedy scenes where fear and laughter collide.

Visually, the film still maintains elements of traditional horror—dark hallways, flickering candles, eerie rituals—but the tension is constantly interrupted by unexpected comedic twists.
Despite the chaos, the story gradually reveals a deeper emotional layer. As the characters struggle to fix their supernatural mistakes, they also confront their personal insecurities and fears.
For Joo-won, the haunting becomes a chance to rediscover the confidence he lost years ago. For Ji-eun, it proves that even imperfect abilities can make a difference when paired with determination.
