# The Serial Killer The story follows a criminal profiler, Inspector Norman (Aeril Zafrel), who investigates a series of murders that appear to be closely connected to one another. He reopens criminal cases that occurred several years ago, and matters become even more complicated when each investigation Norman conducts leads him to another new murder case. Norman becomes increasingly confused as one by one, people he knows are killed brutally, and the killer leaves behind the same clues: a toy figurine called 'Inspector Carlos' and a piece of paper written with 'Case Closed', which is sometimes found within parts of the victim's body. While Inspector Norman is busy conducting investigations with his colleague, Detective Chief Inspector Kelvin Chan (Alvin Chong), he meets Juliana (Siti Saleha), who is the daughter of a successful businessman and owner of Johari Corp, Mr. Johari (Dato' Ahmad Tamimi Siregar).
