Read the complete plot summary and ending explained for Rule No. 1 (2003). From turning points to emotional moments, uncover what really happened and why it matters.
On duty during an assignment, police sergeant Lee Kwok-keung shot and killed Chan Fuk-loi, a serial killer, after Chan crippled his four limbs. When Lee woke up in hospital 49 days later, the police refused to recognise his testimony because it contained information about the supernatural. His superior then transferred him to the Miscellaneous Affairs Department so that he would be on light duty.
Unlike the heroic duty of fighting crime and protecting citizens, the Miscellaneous Affairs deals with unusual cases, which is intriguing and makes people feel lost. The head of the Miscellaneous Affairs, Inspector Wong Yiu-fai, is an eccentric and beer-guzzling man. Wong and Lee work together for the Miscellaneous Affairs to solve an unusual request: to eliminate the fear of every citizen seeking help. While carrying out their duties, Wong pretentiously tells Lee the first commandment of the Miscellaneous Affairs: There are no ghosts in this world! In fact, this first commandment is just a lie. The primary task for the Miscellaneous Affairs of dealing unusual cases is to conceal supernatural incidents from the community to reduce social panic.
Just when Wong and Lee take over the case of the Saint Austina High School massacre, Chan Fuk-loi’s ghost possesses Lee’s wife, May, while Lee is possessed later. The possessed Lee shoots and kills Wong and other colleagues and then makes up his own story to deceive the police.

In the wake of a heartbreak, Caroline finds herself thrust from a familiar routine into an unexpected living arrangement with her estranged sister, Sarah. The cramped apartment they share becomes a micro‑cosm where old grievances mingle with the promise of new beginnings, and the sisters’ contrasting personalities set the stage for both tension and tenderness. Sarah offers a tiny room and a bold pledge: to help her sibling locate the elusive “Mr. Right,” a mission that feels simultaneously hopeful and absurd.
The world of the film is a bustling urban landscape that feels both intimate and overwhelming, where coffee shops, dating apps, and noisy streets serve as backdrops for a series of hilariously uncomfortable encounters. As Caroline steps into a parade of first dates—ranging from polished pick‑up artists to adrenaline‑seeking extreme‑sport enthusiasts and even a karaoke‑loving stockbroker—the tone swings between witty banter and genuine awkwardness. These moments are painted with a light‑hearted, slightly irreverent brush that keeps the audience laughing while still sensing the underlying yearning for connection.
Beyond the comedy of mismatched matches, the story gently explores the rediscovery of family bonds. The sisters, once distant, are forced to navigate shared spaces, conflicting habits, and the lingering echo of past misunderstandings. Their evolving dynamic hints at a deeper, more personal quest than simply finding a partner, suggesting that the true journey may lie in reconciling with each other and with themselves.
Through a blend of sharply observed humor and heartfelt moments, the film invites viewers to wonder how far we’ll go for love—whether romantic or familial—and what surprises await when we finally let the walls we built around our hearts begin to crumble.
