Ching is a forensic psychiatrist who has the power to enter a person’s subconscious. On her latest case, she suspects that another psychiatrist is responsible or a brutal murder-suicide involving a social worker. While investigating the case with a police detective, Ching finds herself under suspicion as she comes face-to-face with a trauma from her own past. Stylish and gripping, Glenn Chan’s directorial debut is a breathtaking psychological thriller about the evil that is subconsciously embedded in our minds, and the terrifying consequences that ensue when the evil is unleashed.
