Chalinee, a young TV reporter, is making a documentary about a famous 6-years old murder case in which a doctor killed his wife. It was big news at the time, because the murderer was a well known professor working for a famous medical institute in Bangkok. As Chalinee researches the case, she discovers two other murders that share many similarities to the first one. 8 years before, a medical student killed his girlfriend in a fit of jealousy and sliced her body into small pieces. In another case that happened forty years before, a nurse was murdered by her own lover, a doctor.
