Season 1

After Police Chief Tuan Lee is murdered, Nangang's biggest triad, Yi He, is plunged into unprecedented crisis when the newly appointed chief started targeting them.

Ah Han & Ah Bing quarrel over whether Yi He should "turn clean" and part on bad terms. When the smuggled goods are hijacked, Ah Bing survives an ambush thanks to a student.

Mr. Liang presents Yi He with an ultimatum: help him traffic drugs or face the consequences.

Ah Han calls for a council meeting but finds the elders fearful and unwilling to fight.

After being framed, Ah Qiang storms Yi He in anger, just as an assassin arrives to kill Ah Bing. Everyone mistakenly believes Ah Qiang sent the killer, and Yi He launches a manhunt against him.

Desperate, Ah Qiang steals Yi He's cash to defect to Liang's group & accidentally kills Fat Uncle in the process. Meanwhile, Uncle Bang expresses the desire to quit, stirring more discontent.

Yi He manages a drug smuggle operation, only to discover the shipment has been swapped. As Ah Han falls into frustration, Praba arrives. He reveals the trap to expose the mole inside the police.

Praba suspects Uncle Fang is the mole & finds out that his son is a drug addict that owes the loan sharks. Meanwhile, Ah Han approaches Red Hair, hoping to form an alliance against Liang.

Ah Kun learns about Ting Ting’s assault and the humiliating video. Enraged, he confronts Big Bear, who accidentally dies after falling onto a sharp object. Panicked, Ah Kun seeks Ah Bing’s help.

With Angie & Red Hair in control, Ah Qiang reappears, revealing that the 3 have been in cahoots all along. Angie forces Ah Han to relinquish leadership to Ah Qiang & holds Ah Bing hostage.

Ah Han meets with Praba, hoping to join hands with the Chief Police. Praba initially doubts him, until Tuan Lee's widow delivers documents proving Ah Han's undercover identity.

Angie grows suspicious of Ah Han and begins investigating him. Ah Qiang's pursuit of profit attracts the younger members, while older members refuse to cooperate.

Following Ah Han’s suggestion, Ah Qiang takes Angie to pay respects at the memorial hall, only for Vivian to appear with a tied-up Zhong Ge exposing all their crimes.

Angie, refusing to accept defeat after Ah Han regained control of Yi He, sends killers after him. However, it is Angie who is assassinated, while Ah Qiang kills the hitman and escapes.

Ah Qiang exposes Ah Han’s undercover identity, turning everyone against him. He believes this will restore him as leader, but the elders appoint Ah Bing as Yi He’s new boss instead.
