Master killer The Killer Meteor has a secret weapon. His skills, plus this weapon, earn him fear and respect. Hardened criminals pay him tribute, and he allows them to live another year, provided they refrain from killing.
Killer M is hired by wealthy Wa Wu Bin to murder Wa's treacherous wife, Lady Tempest. Lady T has slipped poison into Wa's soup and, without the antidote she possesses, Wa would die. Killer M is also to retrieve the antidote. But Killer M is also a secret agent, employed by Lord Fung, who is trying to obtain evidence against Wa. To reach the box containing the antidote, Killer M must masquerade as the slave of Lady T's good friend, Madam Phoenix. Further, there are Lady T's four skilful guards to contend with.
But as the plot unfolds, many of the characters prove to be something other than what they seem. Killer M never even knows whether characters who die, or kill themselves, are actually dead, and if they'll come back to fight again.
When all the trickery, and the plans within plans within plans, are stripped away, Killer M finds that early all the characters he encounters have one aim in common......
