In a run-down, suburban Bangkok hospital, young Dr. Tar and seven nurses have been running a scheme to sell dead bodies on the black market. However, one nurse, Tahwaan, has found out that her boyfriend, Dr. Tar, has been having an affair with her sister, Nook. Growing tired of the body-selling scam and enraged by her sister and boyfriend's betrayal, Tahwaan threatens to call the police. However, before Tahwaan can take action, the doctor and six resident nurses at the hospital strap Tahwaan to an operating table, kill her, and then wrap her in a black plastic garbage bag. They then dump her in the trunk of the doctor’s car, where her corpse will be kept on dry ice until it can be sold. However, Tahwaan spirit comes back and starts haunting them.
