Infernal affairs 2002

Infernal Affairs is a 2002 Hong Kong crime-thriller film directed by Andrew Lau and Alan Mak. It tells the story of a police officer who infiltrates a triad, and a police officer secretly working for the same gang. The Chinese title means "The Unceasing Path", a reference to Avici, the lowest level of Hell in Buddhism, where one endures suffering incessantly. The English title is a word play, combining the law enforcement term "internal affairs" – typically the division of any law enforcement agency that would be responsible for (among other things) finding a mole – with the adjective "infernal", meant in this case as a reference not to fires or infernos in general, but specifically to the inferno of Hell ("Inferno" being the Italian word for "Hell"). Thus, the English title is both a phonetic pun and – like the Chinese title – an allusion to a place or condition of eternal suffering. Infernal Affairs is the first in the Infernal Affairs series and was followed by Infernal Affairs II and Infernal Affairs III.

Chan Wing-yan, a police officer, goes undercover into a triad. Around the same time, Lau Kin-ming, a triad member, infiltrates the Hong Kong Police Force. Each mole has been planted by the rival organisation to gain an advantage in intelligence over the other side. The more the moles become involved in their undercover lives, the more issues they have to cope with.

The prologue opens with triad boss Hon Sam sending a number of young gangsters to the police academy as moles, among whom is a young Lau. Concurrently, a young Chan joins the police force but is seemingly expelled from the academy even though he manages to impress Superintendent Wong Chi-shing. In reality, Chan has become an undercover agent reporting only to Wong. Over the course of ten years, Chan experiences great stress from his undercover work while Lau quickly rises through the ranks in the police department. The film begins with a meeting between Chan and Lau in a hi-fi store without either of them knowing the other's true identity.

Wong and his team interrupt a deal between Hon and a Thai cocaine dealer after receiving a tip-off from Chan using Morse code. However, Lau alerts Hon, giving him enough time to order his minions to dispose of the cocaine, eliminating solid evidence of the drug deal. After the incident, Wong and Hon both know that they each of them has a mole within their respective organisations, placing them in a race against time to root out the other mole. Lau is tasked with finding the mole in the police. Later, Chan sees Hon conversing with Lau in a cinema but does not see Lau's face clearly. He tries to follow Lau and find out who he is, but gets distracted by a phone call. By this time, both Chan and Lau are struggling with their double identities – Chan starts losing faith in himself as a cop after being a gangster for ten years; Lau becomes more accustomed to the life of a police officer and he wants to erase his criminal background.

At their next meeting, Wong intends to pull Chan out of undercover work for fear of his safety. They are unaware that Lau has his subordinate, CIB Inspector B, tracking him. Lau relays Wong's location to Hon, resulting in Hon's henchmen being sent to confront Wong. Lau relays Wong's location to Hon, who sends his henchmen after Wong. Inspector B informs Lau of the henchmen's arrival, and an OCTB squad is dispatched to save Wong. Chan successfully flees from the building; Wong is caught by Hon's men and is killed when he is thrown off the building, having refused to reveal Chan despite the beating from the gangsters. As the police close in, a shootout ensues in which several gangsters are killed. Keung drives Chan away from the scene, but later dies from a gunshot wound. It is reported on the news that Keung was actually an undercover cop; Hon assumes that Keung was the mole and that Chan killed him to protect the triad.

Lau retrieves Wong's cell phone and contacts Chan; both of them agree to foil a drug deal by Hon. The plan succeeds and many of Hon's men are arrested, while Lau betrays Hon and murders him. Everything seems to have returned to normal – Chan can revert to his true identity as a cop, while Lau has erased his criminal connections by eliminating Hon's triad. However, back at the police headquarters, Chan discovers that Lau was the mole and leaves immediately. Lau, realising what has happened, erases Chan's file from the police database. Chan spends an evening with his psychiatrist, Lee Sum-yee, with whom he has fallen in love. He sends to Lau a compact disc containing recordings of phone calls between Hon and Lau. Lau's fiancée, Mary, plays the disc, finds out about Lau's criminal connections, and expresses her disappointment with him.

Chan and Lau meet on the same rooftop where Wong was killed earlier. Chan disarms Lau and holds a pistol to his head as a rebuke to Lau's plea for forgiveness and request to remain as a cop. Inspector B arrives on the scene shortly and orders Chan to release Lau. Chan holds Lau as a hostage at gunpoint and backs into the lift, but upon moving his head from behind Lau he is suddenly shot in the head by B. B then reveals to Lau that he is also a mole planted by Hon. As they take the lift down to the lobby, Lau kills B out of his desire to eradicate traces of his past, become a "good guy" cop, and end the mole hunt.

Stepping out of the lift, Lau shows his identity card to the police to identify himself as one of them. Months after Chan's death, Lee discovers records revealing Chan's true identity as an undercover police officer; B becomes a scapegoat for Lau as the real mole in the police force and the case is closed. Lau salutes Chan at his funeral. A flashback reaffirms the point that Lau wished he had taken a different route in life.

In mainland China, an alternative ending for the film was created. Lau exits the lift and is informed by the police that they have found evidence that he was a mole. Lau hands them his badge and is arrested without protest. The sequel, Infernal Affairs III, uses the original ending instead of the alternate one.

    Although not included in the soundtrack, Tsai Chin's (蔡琴) song "Forgotten Times" (《被遺忘的時光》) features prominently in this film as a recurring element of its storyline, and also in its sequels. As well as serving to elucidate the theme of the films, the song plays an important plot function in chronologically connecting various elements of the story. The (a capella) song can be first heard when Chen and Lau meet in a store, as they are analyzing hi-fi equipment.


    The success of the film followed with a prequel and sequel. An open-world video game titled Sleeping Dogs (or True Crime: Hong Kong before canceled by Activision Blizzard in 2011) was heavily inspired by Infernal Affairs, with the protagonist of the story infiltrating the criminal underworld as an undercover police.

Lau Kin-ming asks Hon "Why do we always meet in a cinema?", to which Hon answers "It's quiet. No one comes to movies". Cheung comes out from the shadows behind them and says "I don't know...quite a few people watch movies" and we see a slew of Hong Kong celebrities watching various clips of Hong Kong films on the screen. Originally Tony Leung was going to appear but scheduling conflicts led to the recasting.
