Monga

Monk kills Geta because Wim-Kian manipulates him into believing the waishengren (mainland Chinese) gangsters are taking over Monga and that Temple Front's power is crumbling. Wim-Kian orchestrates the assassination by convincing Monk it's inevitable, positioning Monk to shoot Geta while Wim-Kian himself kills Masa. This betrayal is part of Wim-Kian's broader scheme to destabilize Temple Front and install his own control through the Princes.

Earlier, Monk overhears Geta and Masa discussing past conflicts, revealing the violent history behind the gang power struggles.

Grey Wolf discovers his paternity through a postcard he sent to Ling-wan (the woman who runs the beauty salon) years earlier. The postcard resurfaces, confirming that Mosquito is his biological son. This revelation comes just as Grey Wolf learns Wim-Kian plans to ambush Mosquito and the Princes in the Philippines, prompting him to rush to stop the betrayal.

Wim-Kian orchestrates the Philippines trip as a trap to eliminate the Princes. After Monk stays behind in Monga, he convinces the other Princes to lay low in the Philippines. Unbeknownst to them, Wim-Kian's men set up an ambush to wipe out the entire gang. Grey Wolf discovers this plan after learning he's Mosquito's father and rushes to prevent the massacre.

Wim-Kian manipulates Monk from the mountains training scene, gradually turning him against Temple Front.

Monk betrays the Princes because Wim-Kian manipulates him into believing the waishengren are destined to take over Monga's gang territory. Wim-Kian convinces Monk that fighting against this shift is pointless and that he should align with the rising power. This manipulation leads Monk to participate in killing Geta and later in the scheme to ambush his own brothers in the Philippines.

Monk overhears the conversation between Geta and Masa about past power struggles, planting seeds of doubt.

Mosquito is severely wounded during the final battle at Qingshui Temple. After confronting Monk and being stabbed, he pursues Monk through the streets. He uses a hug to create a moment of compassion, allowing Dragon to strike Monk from behind. Dragon and A-po then drag the delirious Mosquito away, leaving his fate ambiguous, whether he survives or dies remains unresolved.

The final flashback shows Mosquito hesitating at the school wall before choosing to join his friends, emphasizing the bond that defines his journey.

After being beaten by Geta for the Princes' actions, Monk overhears a conversation between his father (the Back Alley leader Masa) and Geta. The discussion reveals their violent past: Geta previously severed Masa's arm to seize control of Temple Front territory. This hidden history explains the deep enmity between the two gang leaders and the cycle of revenge driving the conflict.

Monkey witnesses Wim-Kian and Grey Wolf meeting in secret and tries to report back to Mosquito. However, Wim-Kian's men discover him and beat him into a coma. This attack is meant to silence Monkey and prevent him from revealing Wim-Kian's conspiracy with Grey Wolf.

Grey Wolf attempts to stop the ambush after discovering through the postcard that he is Mosquito's biological father. Learning that Wim-Kian plans to kill Mosquito and the Princes in the Philippines, Grey Wolf rushes to protect his son, overriding his previous scheme to expand his power into Monga.

The Princes kill Dog Boy in retaliation for him raping Xiao Hui, who is Dragon's girlfriend. Dog Boy committed this crime as revenge for Geta ordering the finger severing of his father Doggy. The Princes kidnap Dog Boy, torture him to death, and this act intensifies the cycle of vengeance between the gangs.

Earlier, Geta orders Doggy's finger severed for cheating on Temple Front turf games.

On Mosquito's first day at the troubled Monga high school, he refuses to bow to Dog Boy's taunts, a display of defiance that immediately earns respect in the brutal social hierarchy of the school. This act catches Dragon Lee's attention and marks Mosquito's entry into the Temple Front gang orbit, setting the foundation for his alliance with the Princes.

After the Princes kill Dog Boy, Geta disciplines all five teenagers. Out of loyalty to Dragon (whose father is Geta), Monk takes sole blame for the murder, accepting a brutal beating from Geta. This act of loyalty later makes Monk vulnerable to Wim-Kian's manipulation, as he begins to question whether his sacrifice was truly valued.

Mosquito meets Ning, a woman connected to a brothel, while visiting with the Princes gang. A fragile romance develops between them. Before Mosquito departs for the Philippines, he visits Ning one last time and shares a kiss, representing one of the few moments of tenderness in the violent world of Monga.

The final flashback shows the Princes skipping school, with Mosquito hesitating at the wall before joining his friends. Monk offers him a hand to help over the barrier. Mosquito looks back at the life he's leaving as he steps forward with his new brothers. This poignant moment establishes the origin of their bond and suggests that despite the violence and betrayal, the friendship began with an act of loyalty and choice.
