Hong Kong variety show: This gangster is so wicked he's practically wicked.

Gao Qiang wakes up in the bustling underworld of 1980s Hong Kong, tasked with an undercover mission to infiltrate the notorious Wo Luen Shing triad. Armed with the ambition to build a legitimate business empire, he instead finds himself bound to a bizarre "Positive Energy System" that grants him power only when he performs good deeds. While rival gangsters bleed for brotherhood and gold, Gao Qiang channels his inner philanthropist—patriotism, community welfare, and absolute civic duty are his new weapons. While others run from street brawls, he stays behind to hand out receipts and ensure thorough after-sales service. Through a hilarious blend of ruthless underworld ambition and absurdly literal "wholesome" actions, Gao Qiang climbs the ranks from a low-level thug to a titan of industry. Twelve years later, the truth is a blur. A veteran police inspector insists Gao Qiang is more law-abiding than the actual police force. Local citizens praise the triad for finally bringing genuine justice to Hong Kong Island, and the media struggles to define the man who revolutionized organized crime with a smile, a receipt, and an iron fist.
