Dangerous Encounters of the First Kind

Paul, Lung and Ko build a wristwatch bomb and set it off in a movie theater as a disturbing prank. The blast triggers panic and attracts police attention, but no one is killed. This act marks the start of the boys’ dangerous escalation.

Wan-Chu is fired from a printing press after a fight and has a bitter relationship with her police-officer brother Tan. She tortures animals, including impaling a cat, and then uses intimidation to force her way into the trio. She manipulates them by forcing the discard of her tortured mouse and challenges them to plant a bomb in a public restroom.

The trio agrees to let Wan-Chu lead, and she places a bomb in a public restroom to prove her capability. The action demonstrates her willingness to escalate violence and solidifies her grip on the group. The restroom bomb becomes a symbol of their new dynamic.

Wan-Chu forces the group to help hijack a bus full of tourists departing from an airport. The plan spirals out of control when the bus door closes with Wan-Chu inside, leaving the others behind. She threatens to detonate a bomb, forcing the tour guide and passengers to strip before she abandons them at a construction site.

Wan-Chu steals a package of Japanese money orders from a foreign gunrunner's car, triggering a chase and drawing attention to their operation. She carelessly drops a contract in an alley, which keys Nigel’s gang into their activities. The gunrunner Bruce is eventually killed by his boss for becoming exposed.

Paul tries to exchange one of the money orders at a bank, but panic prompts him to leave when the teller must consult the director. The youths threaten the bank's exchange manager to reveal information, but he provides a fake address. They plant a bomb under the manager’s car, killing his bodyguard and drawing police attention and linking the attack to Paul’s earlier attempt.

Police link the bank bombing to Paul’s earlier money-order exchange attempt as survivors testify. The investigation widens, drawing in Wan-Chu and the boys, and the police start focusing on their possible involvement.

Wan-Chu is captured by Uncle Hark and his gang during their extortion. Tan arrives and beats up Hark, but Wan-Chu refuses to press charges. The confrontation leaves Wan-Chu under Hark’s control once again.

Back at their apartment, Tan disciplines Wan-Chu with violence and ties her to bars. Later, Nigel's gang tortures Hark to learn Wan-Chu's whereabouts. The intruders come to Wan-Chu’s flat, prompting a chase that ends with Wan-Chu being fatally impaled on a fence post.

With Paul’s image on TV linking the bombings, the three boys flee to a cemetery to escape pursuit. They initially argue over what to do next and attempt to drink Dettol to end their lives, but Ko swallows it while Paul and Lung resist. Paul races to buy milk to dilute the poison, and a milk seller informs Tan that he’s seen them at the cemetery.

While the trio debates their fate, Tan attacks two Mormon missionaries on the street, mistaking them for Nigel’s gang. The misstep lands him off duty for a few days, delaying the investigation. A milk seller later confirms Paul has been seen at the cemetery, triggering a renewed pursuit.

During the cemetery pursuit, Lung is shot and dies, and Paul is wounded as the chaos erupts around them. Ko fights back, killing one attacker with a pipe and seizing a gun. Tan shoots Nigel, and Ko finishes the confrontation by firing at Nigel's remaining men, ending the spree with a riotous montage.
