Captain Donnie Yan (Donnie Yen) and Madam Rachel Yeung Lai-ching (Cynthia Khan) are on the trail of cocaine dealers. When she goes off script and gets found by a dockworker named Luk Wan-ting (Yuen Yat-chor) who thinks that she’s an illegal immigrant. He feels bad for her and gives her money and a place to say. As Donnie stays after the criminals, she learns that Luk’s brother Ming (Liu Kai-chi) is being  attacked by criminals that he owes money to. The two fight off the gang and when her cover’s blown, Rachel gets back on the case. At the same time, their partner Peter Woods gets shotgun blasted by the real boss behind all of the drug deals is a CIA officer named Mr. Robinson.

I’ve just explained about the first ten minutes or so of this dense film, one that builds tension and then goes as wild as any of the other movies in this series.

Luk Wan-Ting is a witness to that murder and gets framed for it. He escapes the police and a killer, which sends our heroes after him. She thinks he’s innocent based on their past history and he thinks that he’s not, so we have some tension between our supercops. In fact, things get even tenser when they start to wonder which cops they can trust and decide to hide out with Luk and attempt to get him to testify.

The final fights in this film — once the plot is solved and we can, as they say, get to the fireworks factory — are incredible. The battle between the CIA agent (Michael Woods) and Yen on top of a building has more action than every movie that will come out of Hollywood this year. There’s also a great battle between Khan and karate champion Farlie Ruth Kordica that has the two falling from huge heights and kicking each other repeatedly. Also: if you like glass being broken — I do — this movie will give you all the shattering and smashing of glass that you can handle.

Director Yuen Woo-ping is a name you should already know but if you don’t, he’s the director of Drunken Master, Tiger Cage, Iron Monkey and so many more movies. He also was the fight choreographer of Crouching Tiger, Hidden Dragon, Fist of Legend, Black Mask, the second and third Matrix and Kill Bill 1 and 2. Seeing his name means that you’re about to have your mind absolutely blown.
