So Close is a 2002 Hong Kong action film directed by Corey Yuen, starring Shu Qi, Karen Mok and Zhao Wei. The film’s English title is derived from The Carpenters’ song “Close to You”, which has a prominent role in the film.
Kong Yat-hung is assigned to investigate the case and she manages to track down the assassins. In the meantime, Chow Lui’s younger brother Chow Nung, who hired Lynn and Sue to kill his brother so that he can become the chairman, wants to kill the assassins to silence them. The cat-and-mouse chase becomes more complicated as both the police and the thugs are out to get Lynn and Sue.
Sue has always been playing the role of the assistant by staying on the computer and helping to disable the security systems and giving instructions on navigating the area, while Lynn, who is older and more experienced, does all the field work. Sue is jealous and thinks that Lynn refuses to let her participate more actively because she is less adept, but actually Lynn is trying to protect her sister from danger. Their relationship becomes strained when Lynn falls in love with her friend’s cousin Yen and wants to give up her job and marry Yen. Sue intends to continue her career as a contract killer so that she can prove that she is as good as her sister.
