Plot Progression

1. The Shape Of Nobody — Lau Kin-Ping introduces a life confined by government housing, poverty, gambling, quarrels, and overcrowding. His water metaphor expresses his lack of identity and direction.
2. A Robbery Takes Form — A refund dispute at a convenience store becomes increasingly hostile. A story about a failed robber provokes Lau Kin-Ping to identify with that figure and threaten the store.
3. Humiliation Behind The Counter — The robbery yields only small bills, and the Convenience Store Boss mocks Lau Kin-Ping. The store becomes an absurd and dangerous trap for everyone present.
4. The Explosive Crisis — Grandfather and Big Boss are drawn into a confused emergency involving champagne, scissors, wires, and a device that may explode. Risky instructions and uncertain expertise increase the pressure.
5. Revenge And Erasure — After the crisis, violence and revenge are weighed against the claim that killing cannot remove suffering. The final status discussion leaves the struggle for recognition unresolved.
