Cheev (Thanavate Siriwattanagul) betrays his wife, Lunthom (Woranuch BhiromBhakdi), by having an affair with his employee, Ros (Arachaporn Pokinpakorn). After repeatedly catching her husband in the act, Lunthom begs Cheev to leave her for Ros. But before anything is resolved, Lunthom’s long-suppressed illness resurfaces. When she collapses, Cheev refuses to help—leading to her tragic death. Following her passing, Cheev discovers Lunthom’s will: he cannot bury her until 100 days have passed. Only by fulfilling this strange condition will he inherit her wealth. But honoring the dead proves far more terrifying than Cheev imagined, as Lunthom’s restless spirit begins to haunt him in ways that blur the line between punishment and vengeance.
