So Close (2003)

Brothers Chow Nunn and Chow Lui, two powerful businessmen who own a giant computer company, are facing a tense crisis--a powerful virus is rapidly wiping out their computer network. At the last minute a cyber-friend technician arrives to join in the battle to save the company. The mysterious friend, Angel.com, battles the virus and saves the company. Invited by Chow Lui for a visit in-person, Angel.com arrives in the form of the beautiful Lynn, who is a spokesperson for her company; in actuality, the company is comprised of both Lynn and Sue, a beautiful sister duo. Besides being a computer wizard, Lynn is also a professional assassin with amazing kung fu skills, and is asked to use these skills to carry out a separate mission following her visit to Chow Nunn. All of a sudden, Chow Lui turns up dead, and his younger brother, Chow Nunn is behind the death. Therefore, when an investigation by the young, alluring cop, Kong Yat Hong, starts to point to Nunn, he becomes worried and decides to re-hire Angel.com's Lynn and Sue to perform another hit--in order to prevent the police from being lead back to him.
