The film opens with an intriguing and mysterious event: a spacecraft from another galaxy crashes into a lake in Seoul, South Korea. As the story unfolds, a naked figure emerges from the water and makes its way toward the city, setting a mysterious background for the two contrasting lives that are about to collide.
We are introduced to Sohui and her husband, Mangil. They are recently married and appear to be blissfully in love. Mangil is hardworking, taking on household chores despite his busy schedule, earning him the role of the ideal partner in Sohui's eyes. Sohui, on the other hand, enjoys chatting with friends and indulging in shopping sprees, finding joy in her seemingly perfect life as the "luckiest woman in the world."
Their domestic bliss begins to unravel when Sohui attends a high school reunion where old friends spill secrets, including the shocking tale of Sarah, a former classmate who murdered her husband after discovering infidelity. As she returns home after the reunion, Sohui stumbles upon a missed call on Mangil's phone from an unknown number, leading her down a treacherous path of suspicion regarding Mangil's fidelity.
The Seeds of Doubt
Sohui’s insecurities grow stronger when she discovers messages hinting at a secret meeting connected to Mangil. Distrust consumes her as she researches signs of infidelity. Her belief that Mangil might be cheating deepens when he concocts an elaborate lie about attending a funeral on a date she had planned.
In a desperate bid for truth, Sohui hires a detective, Dr. Jang, to tail Mangil. The detective's findings reveal that Mangil frequents a golf course and a gym, surrounded by women, and possesses multiple marriage certificates, hinting at a darker secret. Shockingly, they even observe him drinking gasoline—a bizarre detail that leaves Sohui reeling.
Unraveling the Truth
When Dr. Jang suggests that Mangil might be an alien, Sohui finds it hard to believe. However, her skepticism wanes when she witnesses him gulping down gasoline. Meanwhile, Mangil, unbeknownst to Sohui, is plotting her demise, lacing her water with poison.
A tragic twist unfolds as Sohui collapses after drinking the poisoned water. As her fate appears sealed and Mangil feigns concern, her miraculous survival after expelling the poison leads to a desperate desire for revenge. Sohui confides in Sarah, and the two begin to plan their counterattack against the man who has turned their lives upside down.
The Master Plan
The plot escalates as Sohui, Sarah, and Dr. Jang devise a scheme to use electric shock to eliminate Mangil. When Mangil arrives unexpectedly, chaos ensues. A malfunction involving a remote control leads to Dr. Jang’s accidental electrocution, further complicating their already precarious situation.
With Mangil still alive and suspicious, the plan unravels as the group’s attempts to trap him culminate in their clumsy confrontations and unearthly turn of luck. They’ll need to dig graves—not just for one body but for multiple victims—while still staying one step ahead of the extraterrestrial threat that Mangil poses.
Race Against Time
The climax of the film showcases the trio's frantic maneuvers to hide evidence and evade the relentless Mangil. With police checks and misunderstandings leading to confrontations with detectives from XCOM, tensions rise, and the stage is set for a showdown.
Dr. Jang, who regains some memories, has developed an antidote to combat the extraterrestrial threat—but it’s a race against time to get it into Mangil's system and expose him for the alien he is.
A fierce confrontation takes place amid the chaos, with Mangil demonstrating his superhuman abilities and the girls desperately trying to escape. Finally, in a breathtaking resolution, Sohui successfully administers the antidote as the story culminates dramatically with Mangil’s demise.
A New Beginning
The film closes a year later with Sohui, Sarah, and Yang-sun enjoying their newfound freedom from the strains of their tumultuous experiences. They have resolved to live independently and cherish each other's company, leaving behind the peril that Mangil brought into their lives. Dr. Jang enters the scene, fully recovered and bringing flowers—a subtle hint at a budding friendship, if not romance.
The conclusion blends unexpected comedy with the seriousness of the previous events, leaving audiences with a mix of relief and contemplation about love, trust, and the extraordinary twists life can take—even when it involves aliens.
