Dreaming the Reality

夢醒血未停

Also known as Blood Sister, Meng xing xue wei ting, Mung sing huet mei ting

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.
