当一场扭曲的一夜情演变成一名连环杀手的恶性谋杀狂潮时，一切都不是表面看上去的那样。
After Hassan discovers Zidik living alone on the streets, he takes him in and cares for him like a son. Zidik now works together with Hassan in the junkyard but both men are stuck in the past. 15 years ago, they lost their loved ones to a virus that turned people violent. Hassan often "forgets" that the virus killed his wife, while Zidik still remembers his sister attacking his mother and his father sacrificing himself to save Zidik. He also often thinks of Zooey, the girl he met at the orphanage he briefly stayed at before being kicked out by the evil Kak Lily. Meanwhile, Dr. Rahman, a disgraced scientist who previously managed to contain the virus, manufactures a new strain of zombie virus to create chaos. Amid this new zombie outbreak, Zidik encounters a zombified Zooey who tries to attack him but she slowly begins to remember who he is. Zidik then gets taken prisoner by Dr. Rahman when the doctor discovers that he is immune to the virus.
