In the tense underworld of Hong Kong's Triad society, the time has come for a new leader to be elected. The film opens against the backdrop of this crucial turning point, focusing on the two front-runners for the position. Lok, a respected and calculating senior member of the society, represents the more traditional path. His main rival, Big D, is a brash and impulsive figure, embodying the modern and ruthless aspects of gang leadership. The election process is steeped in ancient tradition, but the ambitions of the candidates set the stage for a power struggle that threatens to erupt into violence at any moment.

As the election draws near, both candidates deploy a mix of strategy, manipulation, and intimidation to secure their rise to power. Loyalties within the society are tested as members are forced to choose sides. The society's strict codes of honor and loyalty clash with the raw ambition and greed driving the election, revealing the complexities and the dark underbelly of Triad operations. Meanwhile, external pressures from the police and rival gangs add a layer of tension to the proceedings, with the outcome of the election having far-reaching implications for the future of the Triad's influence in Hong Kong.
