While a film crew is making a late Ming era movie, three genuine classical Ming characters - Commander YUAN CHONGHUAN, Minister ZUO GUANGDOU and Eunuch LI JINZHONG - inexplicably wander onto the set. They are confused by the incomprehensible words of the film crew. They then ask production supervisor NG SIU-HA about Emperor Wanli's whereabouts. SIU-HA tells them this is the year 2017 and four hundred years have passed since the time of Wanli. Past events are coming back to the collective memory of the trio. Rewinding to Ming dynasty. To consolidate power, Crown Prince is marrying GUO QIAN, Crown Princess-to-be and daughter of a distinguished noble clan. CHONGHUAN, GUANGDOU and JINZHONG are team members of the matrimonial liaison task force. They have reached rural territory of Peking after days of strenuous traveling. However, Eunuch ZHANG CHENG plots to kill Crown Princess and sends his guards to wait in ambush. The task force gallantly protects QIAN. Amid the scuffles, they unwittingly venture into a foggy forest and QIAN suddenly disappears without a trace. Back to the present, the trio continue to question SIU-HA, who says she is in fact Princess Pearl. To unite Ming and Qing dynasties, GUANGDOU offers SIU-HA a jade pendant as his gesture of commitment. In exchange, SIU-HA offers a lighter as her pledge. GUANGDOU's trio are fascinated by the flame throwing capability of the lighter, which they think is a precious wonder. To save SIU-HA, Security Chief puts on Ming emperor costume and meets CHONGHUAN, who sees straight through him. They eventually find their way out of the studio and reach a busy street in Foshan. Attire of modern people and unfamiliar surroundings further confuse the trio.

Wai-Chi recruits a chef for Fung Ming Gui; they run into Yi-San who has come for TVC production; Siu-Ha hires the trio as extras.

Wai-Chi gets Zhang Cheng drunk and chains him up; Ka-Hin offers to be temporary head chef; Siu-Tung is recovering from loss of sense of taste.

Watching TV, TAI-KWAN's trio learn YI-SAN is about to return to Hong Kong. They tender their resignations to SIU-HA as they want to go to Hong Kong to find YI-SAN, but SIU-HA refuses. WAI-CHI manages to catch up with SIU-TUNG at the studio. She invites the trio to work for Fung Ming Gui, but with the condition that SIU-TUNG must sign a three-year contract. Realizing they think a three-year term is too long, WAI-CHI lies to them that YI-SAN is her buddy. Phony remarks of CHU KWOK-FUNG, chairman of Dynasty Group, boasting about his culinary skills on TV truly disgust WAI-CHI's father FONG TIN. KWOK-FUNG contacts TIN to discuss buying Fung Ming Gui and points out memory of LAU LEUNG, Fung Ming Gui's chef, is deteriorating. In retaliation, TIN says LEUNG's mind is as sharp as ever. KWOK-FUNG deliberately challenges Fung Ming Gui to deliver their signature gourmet extravaganza The Golden Feast. SIU-HA and the entire staff bid TAI-KWAN's trio farewell. The three sworn brothers are really amazed by the sight of planes and bullet trains, which they have never seen before. CHU KA-HEEN, son of chairman of Dynasty Group, has a date with YI-SAN, who in fact tries to tempt him.

Accompanied by TAI-KWAN, WAI-CHI goes to convenience store for some shopping. On the way, they are disrupted by vicious gang fights. TAI-KWAN helps DING HAU fend off the attackers. As WAI-CHI knows HAU is the boss of Chung Ching Society, so she grabs TAI-KWAN and they quickly flee. Media reports on KA-HEEN pursuing YI-SAN hugely annoy KWOK-FUNG, who instructs Group CEO CHEUK WAH to handle this matter. CHEUK WAH then tells WAI-LING to revoke all contracts with YI-SAN. TIN introduces SIU-TUNG to the kitchen staff. TIN complains about WAI-CHI being misled by SIU-TUNG. LEUNG appears confused when he describes recipes for The Golden Feast. WAI-CHI realizes she cannot rely on LEUNG. TAI-KWAN and YAT-BO accuse WAI-CHI of cheating them by pretending to know YI-SAN. The trio quit on the spot. CHEUK WAH plays his trump card by declaring if YI-SAN and KA-HEEN continue their affair, Dynasty Group will seek another successor. During a press conference, YI-SAN declares that KA-HEEN is purely a business partner.

YI-SAN phones TAI-KWAN's trio and orders them to go to Kowloon City. She tells them the Manchurians are plotting to overturn Ming dynasty. The Manchurians have sent their agent to make secret deal with gangster big shot Mountain Leopard, and the trio must prevent the two parties from forming a union. TAI-KWAN uses his signature kung fu maneuver Immeasurable Ocean, which totally wipes out Mountain Leopard's gang. TAI-KWAN then realizes Mountain Leopard is actually HAU, the boss of of Chung Ching Society, who he once saved. HAU offers TAI-KWAN's trio to work for him, but they refuse. YI-SAN comes clean by saying she is not Crown Princess and persuades the trio not to contact her again. TAI-KWAN plans to leave Fung Ming Gui and return to Foshan to look for Crown Princess. WAI-CHI is relieved by SIU-TING's willingness to prepare The Golden Feast. She also begins to believe they are Ming people. In a TV studio, KA-HIN questions YI-SAN whether she has any non-showbiz boyfriends. Meanwhile, YAT-BO is attracted by the noise and goes to the scene. WAI-CHI announces preparation of KWOK-FUNG's banquet is aborted and Fung Ming Gui will close.
