Kidstuff Sammo Hung Kam-Bo is pulled into a tense caper when police superintendent Walter Tso Tat-Wah asks him to unravel an international arms trade linking two dangerous factions. One side is a Japanese Yakuza cell in possession of stolen diamonds, while the other is a shadowy group of terrorists hoarding ammunition. The case threads through the city as Kidstuff pieces together the motives and routes, all while keeping his own street-smarts sharp and his nerves steady.
At the local police station, Kidstuff crosses paths with an old friend, Sylvia Chang as Quito, sparking a reunion filled with warmth and a bit of awkward humor. Their embrace draws the wrong kind of attention from some passing officers, who rush to tell Quito’s husband, Karl Maka — a man who would rather bend rules than listen to reason. The moment sets off a ripple effect that colors the rest of the investigation with misread signals, jealousy, and a stubborn pride that both clouds and sharpens judgment.
Feeling the weight of the task, Kidstuff tries to rally the famed Lucky Stars, tapping into a history-rich network that once relied on his leadership. He reaches out to the group’s core members, including the seasoned icons Eric Tsang Chi-Wai, Richard Ng Yiu-Hon, and Stanley Fung Shui-Fan, alongside the fresh energy of Michael Miu Kiu-Wai. But the former allies have drifted into new criminal enterprises, and generosity of the old crew isn’t guaranteed. Not giving up, Kidstuff forges a plan with a brand-new crew, mixing grit and humor as the team comes together.
The recruitment drive is a colorful mix: Top Dog Alan Tam earns his nickname for his uncanny rapport with dogs, while Fat Cat Kent Cheng Jak-Si joins on a streetwise instinct and a pocket full of money. Lambo Andy Lau brings martial-arts prowess and a knack for charm, and Long Legs Anthony Chan Yau and Libbogen Billy Lau Nam-Kwong round out the duo of cautious cops who fear chaos as much as they crave action. Rounding out the roster is Yum Yum Maria Tung Ling, tasked with teaching self-defense and disguise, a mission that becomes almost as much about surviving the journey as about the skills themselves. The training montage lands with a comic whiplash, as their busy escapades and flirtations with danger interrupt every lesson and render the trio of techniques laughably unlikely to stick.
Their mission escalates when the gang, posing as Arabian clients, moves into Fushime’s villa to broker a deal. Fushime is a key player in the diamonds plot, and the crew is welcomed to stay for a night. While inside, they slip into the safe, locate the diamonds, and, in a ridiculous twist of fate, swallow them to avoid capture—only to trap themselves inside the very safe they hoped to plunder. When Kidstuff learns of their predicament, he pleads with Walter Tso Tat-Wah to organize a rescue, but the response is chilling: the higher-ups would rather keep the operation quiet than risk exposing the public to a gun-running scheme. Kidstuff ends up imprisoned in a mental hospital, and the exasperated Albert Karl Maka resurfaces as a formidable antagonist.
Back at the villa, the rescued crew finds their footing again. Lambo confronts Fushime in a heated duel, while the rest of the group battles through Fushime’s top henchman and other goons, turning a tense siege into a showcase of frantic action and teamwork. With Kidstuff free to lead, the balance shifts decisively. He and the others close in on Fushime, and the final confrontation tightens into a personal test of loyalty and resolve.
In the climactic clash, Albert returns with a taunt that drives the plot toward a dangerous ultimatum: a dramatic game of Russian roulette is proposed to prove love and loyalty. The tension crackles as Kidstuff takes Albert’s revolver and fires five times into the empty chambers, insisting that Albert do the same to prove his devotion to Quito. Albert scoffs at the idea, arguing that his life carries greater weight than his marriage, a claim that Quito overhears just as she arrives and delivers a decisive, corrective slap that snaps the situation into perspective.
What begins as a chaotic caper spirals into a portrait of loyalty, betrayal, and the stubborn bonds that tie a group together in the face of danger. The film blends fast-paced action, physical comedy, and a touch of romance to deliver a story where an unlikely team learns to trust each other, even when miscommunications threaten to derail everything they’ve come to stand for.
