Ruby Ko Pui-Yee

A mortician seeks revenge against a serial killer who has murdered her sister. However, there is a case of mistaken identity and she begins to target her psychiatrist instead.

An expert assassin - trained since childhood to be the perfect killer - loses her memory during a mission in Thailand, and ends up in the care of a wry ex-policewoman and her boxing cohort. The equally lethal sister of the assassin pursues her, uncertain of her intentions and whether to kill her.
