Two detectives who are up to their necks in trouble and in each other's face, as they try to shut down a drug-trafficking scheme that could be connected with international ties to organized crime. But in the mist of their investigation, innocent immigrant dock worker Luk Wan-Ting gets caught up in the mix when he witnesses the murder of an intelligence operative and is framed for the crime. After escaping police custody and after his friend is brutally killed by hired assassins in search of a film negative that Luk lost, he has no choice but to return to Hong Kong until the heat cools off. Donny and Penny Yeung are called in to extradite him with the aid of Captain Michael. Penny believes that Luk is innocent and tries to do everything in her power to help him, while Donny who is skeptical about Luk's innocence, thinks he's guilty and does his best to snap the cuffs on him. As the two do more investigating, they learn that the drug cartel could have connections with rogue C.I.A. ... Written by Keno Reeves (spywatcher459)

User Reviews

don't expect a storyline - enjoy the action.
21 February 2004 | by bavski-knovrilSee all my reviews

Silly amounts of fights beak out. one guy has a balisong and is stupid enough to take on cynthia (who is armed with spanner-nunchaku).

You could probably watch this with the sound turned off and not miss out on anything.

If you want action, watch this movie. However, don't expect this one to bring you to tears. If this film was a book, it would be an inflatable bath-time storybook, one word a page, accompanied by illustrations...

but what illustrations!
