In a run-down, suburban Bangkok hospital, young Dr. Tar (Wichan Jarujinda) and seven nurses have been running a scheme to sell dead bodies on the black market. However, one nurse, Tahwaan (Chol Wachananont), has found out that her boyfriend, Dr. Tar, has been having an affair with her sister, Nook (Chidjun Rujiphan). Growing tired of the body-selling scam and enraged by her sister and boyfriend's betrayal, Tahwaan threatens to call the police.
