Guangzhou city, a blackmailer is killed in his flat by a figure wearing a motorcycle helmet who takes the man’s mobile phone and a camera’s memory card with nude pictures of a young woman. Yang Bowen, a young man in his 20s who’s still haunted by the deaths of his father and mother at home 10 years ago, moves out from living with his maternal aunt into a big modern flat. Almost immediately he’s attacked by Helmet Man, who leaves behind a family photo with the faces of Yang Bowen’s parents scrubbed out. Meanwhile, Xia Zixi, spokeswoman for the successful online game Horrible Neighbour, has an argument with her lubricious boss, Zhou Zhifeng, over wearing scanty clothes for a publicity shoot and storms off home. Helmet Man snaps her in the shower and then attacks her; she asks help from her neighbour.
