Junchai, the daughter of a police officer, harbored vengeance ever since she was a child because she saw her father shot to death in front of her eyes by a gang of drug dealers. Parndeun and Tiwa also came from a police family and had their father killed the same way. Parndeun and Tiwa's mother, Nuan, took Junchai in as her adopted daughter. The three children loved each other very much as if they were blood siblings, and the two younger kids looked up to Junchai as the older sister who would take care of her younger siblings.
