A secret government agency arranges for the shooting and abduction of a young woman (Jade Leung) who is deemed a worthy candidate for training as an assassin. She is physically revived with a computer chip implanted in her brain to ensure compliance, if needed – although this features very little in the plot. Brought to a high pitch of operational readiness by her trainer and controller (Simon Yam) – who seems to have more than just a professional interest in his pupil – the agent is released into the community and returns to HK to await activation. There she meets a wildlife conservationist with whom she forms a relationship that brings temporary happiness until she is ordered on a mission to Japan. This finally exposes her secret role to her lover, placing his life in immediate jeopardy. She is ultimately faced with a seemingly impossible choice to which she responds with violent decisiveness.
