In a small and gloomy cemetery, a new land administration director encounters a peculiar map where each section is marked with a color indicating whether the land is sold or not. Accidentally playing with the markings on the map, he begins to cross lines he shouldn't. Every time he places a black nail in an empty plot, he receives chilling news that the corresponding person has died, leading to a terrifying chain of events that makes him question his sanity.

As the days go by, his failures and the pressure from those around him increase, as he begins to lose the ability to distinguish between the real and the supernatural.

The plot becomes increasingly distressing, trapping the viewer in an atmosphere of paranoia and mystery. With unexpected twists and a tension that feels ever heavier, the protagonist's desperation becomes a reflection of the struggle between fate and free will, leading to an unsettling climax that will leave everyone breathless.
