Dangerous Encounters of the First Kind

Wan-Shu doesn't report the boys because she sees an opportunity for power and excitement. After being fired from her job and having a conflicted relationship with her police-officer brother Tan, she gravitate toward the criminals as a way to assert control over her life. By threatening to expose them, she forces her way into their group, gaining the thrills she craves while avoiding accountability for her own crimes.

Wan-Shu's animal torture establishes her sadistic nature and foreshadows her violent downfall. She impales a cat on a fence post in a moment of spite, displaying cruelty without remorse. This behavior reflects her desire for control over living beings and sets up the film's ironic ending where she dies the same way, impaled on a fence post by Nigel gang members.

The cat impalement early in the film directly mirrors Wan-Shu's death scene.

Wan-Shu is abducted by Nigel gang members and dies when she falls, being impaled through the head on a fence post. This is a direct mirror of how she earlier impaled a cat on a fence post in cold blood. The film uses this poetic justice to underscore the theme of cyclical violence, her cruelty literally returns to destroy her.

The cat impalement scene establishes the exact method of her eventual death.

Wan-Shu steals Japanese money orders from Bruce, a foreign gun runner. While escaping, she drops a contract in an alley that exposes their operation to Nigel. Bruce is later killed by his boss Nigel for compromising the operation. The boys attempt to cash the orders at a bank but panic, leading to a bombing that kills a bodyguard. The money ultimately causes conflict between multiple criminal groups and is scattered during a parking garage fight.

After Paul's face appears on television as a bombing suspect, the three boys flee to a cemetery knowing they have no escape. Overwhelmed by despair and the weight of their crimes, they decide to drink Dettol poison rather than face capture. Ko actually swallows the poison while Paul and Lung spit theirs out, forcing Paul to frantically seek milk to dilute the toxin and save Ko's life, ironically drawing attention to their location.

Tan, a police officer and Wan-Shu's brother, mistakenly attacks two Mormon missionaries on the street, believing they are Nigel gang members. His paranoid error stems from his obsessive pursuit of the criminals and his desperation to protect his sister. This blunder results in him being suspended from duty for several days, temporarily halting the police investigation into the boys.

Uncle Hark is a local gang leader who runs a club and becomes an ally to Wan-Shu's group. He helps broker a deal with a banker to cash the money orders but then robs the youths of their money. When Nigel tortures Hark to learn Wan-Shu's whereabouts, Hark reveals information under duress, leading the gang to her apartment. Tan later beats Hark at the apartment but Wan-Shu refuses to press charges.

In the cemetery showdown, Lung is shot and killed by a Nigel gang member who is himself shot dead by another enemy. Paul is wounded during the chaos. Ko fights back, killing one attacker with a pipe and seizing a gun. Tan arrives with a machine gun and kills Nigel, while Ko fires at Nigel's remaining men, ending the violent spree. The film closes with a montage of 1967 Hong Kong riots photos.

The 1967 Hong Kong riots montage serves as a contextual frame, showing that the film depicts a period of social unrest and lawlessness in Hong Kong. The closing image returns to an earlier prank, the boys splashing red paint on a pedestrian, contrasting their small-scale mischief with the escalated violence that follows, emphasizing how their petty crimes spiraled into serious criminality.

Wan-Shu forces the boys to help hijack a bus full of tourists leaving an airport. The plan fails when the bus door closes with Wan-Shu still inside, separating her from the boys. Trapped, she threatens to detonate a bomb and forces the tour guide and passengers to strip to their underwear before dumping them at a construction site. She then turns on her accomplices, pouring gasoline on them in an attempted arson.

After Paul attempts to exchange a money order at a bank but panics and flees, the boys threaten the bank's exchange manager for information. He gives them a fake address, so they plant a bomb under his car as revenge. The explosion kills only the manager's bodyguard, not the manager himself. This attack links Paul to the earlier theater bombing through survivor testimony, widening the police investigation.

Tan is Wan-Shu's older brother, a police officer assigned to investigate the theater bombing case. Their relationship is strained, he disciplines her violently and tries to control her. Despite being on opposite sides of the law, Tan protects her from criminal groups and pursues her accomplices. When Wan-Shu refuses to press charges against Hark, Tan beats the gangster, showing his complex, violent approach to family loyalty.
