Psycho

Wan Chai District Patrol Officer Chen Junjie (Eason Chan) has gradually lost enthusiasm for his job as a police officer because he has been doing very regular and unchanging work every day for seven years. When his junior sister Liao Denan (Yung Joey) is sent to patrol with him, he sees that the other party is full of enthusiasm and takes everything seriously. Nineteen-year-old innocent girls Nicole and Diet met Chen Junjie after meeting a bus passenger who exposed weapons, and began to admire him. Chen Junjie also felt warm from the two of them. Soon, a brutal rapist appeared in Wan Chai District. Many single women were raped and killed by him, and Diet was not spared. This incident prompted Chen Junjie to wake up from his numbness, and he began to hunt the murderer frantically.
