In the Line of Duty

Asprin (Mang Hoi) and Strepsil (John Shum), two petty thieves who inadvertently become involved in a murder case when they steal items belonging to a murdered man. The man had hidden an important microfilm in his passport, which the thieves pass onto a forger friend Panadol (Tsui Hark). Inspector Ng (Michelle Yeoh) is assigned to the case, along with Inspector Morris (Cynthia Rothrock) from Scotland Yard. The investigation leads the cops to the bumbling crooks and soon they are on Triad leader Tin's (James Tien) tail, he will stop at nothing to get the incriminating film back and with his hitman and bodyguard (Dick Wei) at his side, he proves too much for the inspectors to catch using legal means, in frustration they give up their badges and go after Tin alone.

Michelle Yip of the Hong Kong police is a mild-mannered Kung Fu expert; Michael Wong, from air security, is happy-go-lucky, stuck on himself, constantly talking, and smitten by her; Yamamoto is quiet, hard-boiled, leaving the Tokyo police to spend time with his wife and daughter. They form an alliance when they foil a hijacking on a plane flying a mob prisoner from Tokyo to Hong Kong. The mobster and his would-be rescuer die, and this sets off two avengers who were their blood brothers. Our three cops become the targets. A high-speed chase, a car bomb, the destruction of a nightclub, a spectacular suicide, dead bystanders, and a flying coffin litter the landscape by the end.

Genji Nakamura and his soul-mate and partner Michiko Nishiwaki are thieves for the notorious Red Army terrorist organization in Japan. After pulling off the jewelry heist of the century (in which dozens of people get killed including a Tokyo detective), they are now planning to use the jewelry they've snatched to buy an arms cache from gun smugglers in Hong Kong for their movement. But when the duo learns the jewelry is fake and that their co-conspirator has set them up, they are determined to get what is owed to them even if they have to tear Hong Kong inside out. But lovely Hong Kong inspector Rachel Yeung is on the scene and she's not having any kind of bloodbath on her watch. After recently being promoted to 'Madam' for the S.C.S. (Serious Crimes Section), Rachel is determined to bust Michiko and Nakamura anyway she can when their violence results in too many casualties. But Rachel finds herself at odds with her bumbling uncle Cameron Chung, the head inspector for the S.C.S., as he feels this case is too dangerous for her and assigns Rachel to be a police escort for Officer Fujioka, a quiet but determined Tokyo police officer who is in town for his own personal reasons...reasons which could spell trouble for Rachel when she learns that he has a personal vendetta against Michiko and Nakamura. As the action hits overdrive filled with chases, gun fights and some serious hand-to-hand combat from both sides, it leads to a brutal but nasty showdown pitting cop against criminal...and only those with something to lose may be the ones to walk away from this encounter alive.

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!
