The film stars Sammo Hung, Simon Yam and Wu Jing, who reunite after 2005's SPL: Sha Po Lang.

Triad boss Lin Ho-lung (Sammo Hung) is celebrating his son's first birthday, a child conceived by his mistress.

Later that night, Tung and Tin-hung torture Tracy, who reveals that the threat was bogus and that her secret lover coerced her into creating a lie so she could flee with him once she had received the money.

After receiving $200 million from Lung, Soso and Fat kill the hired kidnappers and Uncle Yu to cover their tracks.

Lung and Tung eventually start a war against a rival triad gang whom they suspect is responsible for the murder.

Knowing that they will be unable to escape, Tin-Hung mentions that he was never convinced by the stories that claim Lung was an "invincible fighter."

Law then realized that the prequel sequel idea had limited potential, especially when he wanted to show the relationship between the Sammo Hung and Wu Jing characters from SPL.

Though it has themes similar to SPL, and reunites Wu Jing and Sammo Hung, Law’s Fatal Move is a completely original work.

[2] For his film, Law wanted to set his sights on North American audiences, by assembling a cast of familiar actors that are best known to them, such as Sammo Hung, Ken Lo, Simon Yam and Danny Lee.

The film was not given a release in Mainland China, since Law refused to compromise by editing a tamer version that conforms to their strict censorship.
