The eldest, Chadaohorn, is the most beautiful woman one could lay eyes on, unmatched by anybody. The middle, Chadaploy, has an air of free-spiritedness and self-confidence. Finally, the youngest, Chadapetch, is just as mean as she is pretty, and loves to compete with people.
One day, Chadaphorn falls into a canal and dies. The conclusion of the investigation was “accidental death”. However, in reality, it was not an accident but a murder. Someone had chased her and murdered her that night. Now her spirit lingers in the air, holding a deep grudge against the one who caused her death.
