So Close (2002)

Lynn is one of the world's greatest assassins, taking as her targets only criminals she deems deserving of death anyway. Aiding her in this endeavour is her younger sister Sue, who remotely guides Lynn through her missions using satellite spy software invented by their late father, which gives the user the ability to tap into any security system in the world. Their hit on CEO Chow Lui, in his spiffy offices, draws the attention of supercop Yat-Hong. Sue's attraction to the dynamic Detective Hong put them in serious danger.
