1 hr. 43 min.
What starts off as a kidnapping becomes something far more horrific than detective Pit (Tony Leung Ka Fai) could ever have expected. Manson Ma (Lau Ching-Wan), a computer programmer, is reported missing by his family, only to turn up in a house that was once the site of a gruesome murder-suicide. With the perpetrator still on the loose, Pit keeps an eye on Ma and his wife, Amy (Amy Kwok). The programmer, meanwhile, starts exhibiting strange behaviors, as if something inside him has changed.
