The narrative is structured as a nested anthology framed by Da-kyung's interviews with the Gwanglim Stationmaster, covering stories about a head-banging passenger, a smiling commuter, a cursed vending machine, a bandaged cosmetic surgery stalker, a cursed goat doll, an infected handrail, and the 3:34 AM ghost train.
As Da-kyung's video series tops trending charts, real victims and relatives contact her demanding the removal of the footage, warning that the stories carry a living curse. Blinded by vanity, Da-kyung dismisses their pleas, alienates Woo-jin, and returns to the station late at night demanding the ultimate story to secure her channel's legacy.
The Stationmaster reveals that Gwanglim Station is an active portal where a phantom train arrives at 3:34 AM, confessing that he is an orchestrator who delivers self-absorbed individuals to the cursed platform. Da-kyung boards the train to livestream her scoop, but once the doors seal, the passengers materialize as the grotesque specters from all previous stories. The train plunges into darkness with no listed stops as Da-kyung's final video uploads automatically—sealing her viral fame while trapping her forever on the ghost train as the next urban legend.
