Full Plot Details

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. operatives, who could also have someone on the police force keeping tabs on them about their investigation. At this point, Penny and Donny don't know if they can trust their own co-workers or even each other for that matter and Luk's testimony to what he saw poses a threat to the criminals involved in the conspiracy. Now for the next 72 hours, Penny and Donny will have to learn to tolerate each other while trying to protect Luk from the assassins who want him silenced. If they can do that, the bad guys don't stand a chance and they just might all survive this case...if they don't end up killing each other first!

User Review - 10/10 by Geet Dwonderful!!!! paske je comprend le mandarin ehh
User Review - 10/10 by Yassine Dsuper film d'action ! Donnie Yen et C.Khan sont super .. les combats et les cascades regler par Woo-ping Yuen sont comme d'habitude superbes ... A voir et revoir
User Review - 10/10 by Sarfaraz AIt is shame that nobody has reviewed this greatest Hong Kong action film. Loved it so much, wonderful story, with each and every character most notable and worth praise for their brilliant performance!
User Review - 8/10 by Derek LThe rating above is for the action. Obviously this isn't supposed to be a good movie, but the action more than makes up for it. Definitely one of Donnie Yen's best alongside Yuen Woo-ping and co. Cynthia Khan handles herself well too.
User Review - 8/10 by Dave AAwesome action film. Donnie Yen has some great fights, but I personally thought Cynthia Khan stole the show. Amazing stunt-work.
User Review - 8/10 by Alan LHigh octane kung fu action all the way in this impressive HK movie. The pacing is superb. You watch action films for action - and director Yuen Woo-ping keeps the movie going at a breathless pace with a fight or chase almost every five minutes. It's inventive and brutal stuff. The story might not be anything special - a witness to a crime is hunted by both the police and some gangsters but with blistering chop-socky and dangerous stunts from the opening frames to the end credits, those who enjoy Hong Kong mayhem will be in heaven when they watch this. Cynthia Khan who is absolutely amazing gives as good as she gets in the action scenes. She's easy on the eye, can act and fights as well as any man. One of the many highlights featuring her is a scrap on a moving ambulance. Donnie Yen also gets to shine in the action department with several incredible set pieces. This movie has a take-no-prisoners, anything-goes attitude that is unique to Hong Kong action cinema. I loved it and highly recommend it to action fans.

User Review - 8/10 by Camille LMonday, March 26, 2012 (1989) In The Line OF Duty IV: Witness (In Chinese with English subtitles) ACTION/ COMEDY Fourth of 7 or 8 "In The Line Of Duty" movies, starring Cynthia Kahn and Donnie Yen (who at the time signed to do 4 movies with Yuen Woo-Ping) protecting an important witness who has a bounty on his head, unoblivious that there's a corrupt police officer who's trying to take him out as well played by Michael Wong! There's also another sub plot involving a secret negative leaking some corrupt official but the movie would've been over a long time ago, and that it had to be a two hour film. The plot obviously serves nothing but a backdrop to showcase some hard hitting action fights/ stunts except that they could've been better photographed! 3 out of 4
User Review - 6/10 by Gino RI missed the first three but i was still able to pick up on the plot. Mindless cop movie.
User Review - 6/10 by Steve Wold school 80's HK martial art flick. old school donnie yen. good stuff.
