獸性新人類II–失憶性行為

During the murder of her boyfriend, Ann (Sophie Ngan) is hit and loses her ability to remember more than the previous 15 minutes at any given time. But she swears to find the murderer and recall her past with the aid of her tattoos, which provide her with vital information. Starting with a blank canvas, she must make sense of the people around her–a cop, a business woman, a divorcee and a transsexual–in order to put the pieces together. (In Chinese language, with English subtitles).
