Premise

The film follows Nick (Daniel Wu), an undercover narcotics agent who has spent eight years inside a heroin trafficking organization as the protégé of the drug lord Lin Quin, also called Kun or "Banker" (Andy Lau).²^•¹⁰ Kun is suspicious and careful by nature; even his close aide Nick does not know how he manufactures drugs.¹¹ Once Nick finally wins his complete trust, Kun begins to pass on the secrets of his trade, and Nick, having inherited the position, continues tracking the source of the drug supply while acting as a trafficker.³

Two subplots run alongside the infiltration. Nick becomes involved with Fan, also called Jane (Zhang Jingchu), a woman addicted to heroin who lives with her young daughter and an estranged, also addicted husband (Louis Koo).¹^•³ The film also follows the customs and narcotics police team, led by Liu Kai-Chi's customs team leader, as it closes in on the network.¹ The Quebec classification record notes that the film ends with the gang leader's suicide, shown graphically.⁶

The film opens with Nick asking whether emptiness or drugs is more frightening, then recounts in flashback the events that brought him to that question.¹²

Production and research

Origins. Derek Yee said the initial idea came from a character played by Andy Lau, encountered while he was making One Nite in Mongkok (2004), a period during which he talked often with police friends.¹³^•² He described meeting a drug trafficker socially who sat beside him for a long time before speaking, an encounter that left him wanting to portray that life on film.¹³

Research. Yee said he accumulated extensive material before shooting: written and desk research, interviews with many people connected to the drug world, and study of the full history and materials on the Golden Triangle at a museum. He said he used much of his interview notes in the script because he wanted the story's real-world meaning to reach the audience.¹³ The actors did fieldwork of their own: Zhang Jingchu visited a drug rehabilitation center, and Louis Koo, arranged through friends, visited drug users, which Yee credited for the film's realistic effect.¹³

Casting choices. Yee said market considerations came first in choosing Louis Koo, and that Koo agreed to the role within two or three days of reading the script, without objection. Yee engaged a drama teacher to change Koo's acting style and deliberately made his appearance unattractive, since a handsome look would not suggest a drug addict.¹³ When the script first went to Daniel Wu and Louis Koo, both were interested in the role of Fan's husband; Yee chose Koo after weighing the parts.³

Locations and crew. Filming took place in Cambodia and Thailand as well as Hong Kong; a dining scene with Daniel Wu and Zhang Jingchu was shot in Tai Kok Tsui, and was interrupted repeatedly because the child actor's performance was not yet settled, with the two leads spitting out their food at each cut to avoid becoming full.¹⁴^•¹³ Venus Keung Kwok-Man was the director of photography, Eric Kwong Chi-Leung the editor, Peter Kam Pau-Tat composed the original music, and Chin Ka-Lok was action choreographer and car-stunts director.¹^•⁴ Production companies included China Film Group Corporation, Beijing Polybona Film Publishing, MediaCorp Raintree Pictures, Artforce International, and Global Entertainment Group (Asia).¹

Before release, Yee denied that the film was a copy of Infernal Affairs, the 2002 undercover thriller also starring Andy Lau, saying the film was about drug enforcement rather than a mole story.¹⁴

Reception

The film was one of the highest-grossing Hong Kong-China co-productions of 2007, according to a We Pictures company profile.¹⁵ At the 27th Hong Kong Film Awards in 2008 it was nominated for Best Art Direction (奚仲文, 麦国强).³ IMDb records 8 wins and 19 nominations in total, with a user rating of 7.2/10 from about 6,200 voters.⁸

Critical response divided over the film's balance between documentary detail and drama. Reviewers placed it in a tradition of drug-crime films that carry semi-documentary material about sources, middlemen, and end users, alongside Scarface, New Jack City, Traffic, and American Gangster.² A UCLA Center for Near Eastern Studies review praised Wu's portrayal of the undercover officer's guardedness but argued that a third of the film reads as a detailed account of drug-making and trade logistics, drawing attention away from the characters; it noted that real undercover officers were consulted for authenticity.¹² The Eye for Film review found the film unable to settle on a consistent tone, calling the result disjointed melodrama, while singling out the opening scenes and Lau's portrayal of Quin, a sickly man who keeps his distance from his own trade, as strengths.² A French-language review at Cinémasie credited Yee's craft but criticized a moralizing final speech as a consensual addition, while still judging the film above the standard of contemporary Hong Kong productions in its polish.¹⁶ On Rotten Tomatoes the film holds an 83% Tomatometer from 3 reviews.⁹

The film was shown in 2024 in a Derek Yee retrospective, "The Other Current of the Hong Kong New Wave," at the Festival des 3 Continents in Nantes, where programmer Jérôme Baron described it as overlaying several narrative lines and placing its characters before choices they must commit to.⁴
