Aiman is a 28-year-old Malay correctional officer who has recently been transferred to the territory's top prison. He lives with his older sister Suhaila in a modest housing estate. At his new workplace, Aiman begins to take an interest in a 65-year-old sergeant named Rahim. Soon, it is revealed that the charismatic Rahim is actually the long-serving chief executioner of the prison. Rahim also takes notice of the principled and diligent Aiman. When Rahim's assistant suddenly quits, he asks Aiman to become his apprentice.
