So Close (2002)

Lynn and her younger sister Sue inherited their late father's satellite surveillance system and turned it into a tool for contract killing, with Sue hacking cameras and networks while Lynn does the deadly work in the field. After a spectacular hit on a corporate boss, the dogged inspector Kong Yat-hung starts tracking them, and the sisters also become targets of the people who hired them. So Close is a stylish Hong Kong action film from Corey Yuen, a veteran fight choreographer, and its three stars Shu Qi, Zhao Wei and Karen Mok do much of the high-kicking, wire-assisted action themselves. The Carpenters song Close to You runs through the film as a motif, and the climactic office-tower shootout is a highlight.
