Suay Laak Sai (2007)

At a Thai hospital, a doctor and his seven nubile nurses engage in the sale of dead bodies. Jealousy causes one of the nurses to threaten to blow the whistle on the practice, so the others murder her. Soon the spirit of the slain nurse seeks revenge. In flashbacks we see the events leading up to the murder, and realize the full range of relationships between the main characters.
