From Vegas to Macau

Benz, his son Cool, and nephew Ngau-Ngau form a vigilante team that robs gangsters at night and distributes the loot to the needy. Their activities are clandestine, and they keep their secret from Benz's wife, who is suffering from cancer. The team operates with a sense of justice, targeting criminals while hiding their true identities.

Lionel, Benz’s stepson, is working undercover as an employee at the multinational company DOA, which is secretly controlled by the criminal syndicate led by Mr. Ko. Lionel’s mission involves tracking the syndicate’s activities using a camera implanted in his contact lens, which allows him to gather vital intel.

Benz reunites with his old friend Ken, known as 'Magic Hand', who is skilled in gambling and combat. Ngau-Ngau develops an infatuation with Ken's daughter Rainbow, attempting to win her affection despite her rebuffs. Ken, however, prefers Cool as a potential suitor for his daughter.

Lionel discovers that his cover has been compromised. He hides the camera-lens device in a stuffed teddy bear at home, unaware that Ngau-Ngau later gives the bear to Rainbow. This exposes Lionel’s secret to others, endangering his mission and family.

Mr. Ko sends an assassin to attack Lionel’s flat, but Benz, who has just returned home, is caught in the violence. Benz is severely beaten and tortured, resulting in a coma. Lionel's body is later found bearing signs of torture, indicating the level of threat posed by Mr. Ko.

Police detectives from China, Hong Kong, and Macau enlist Ken’s help to take down Mr. Ko, the ruthless criminal mastermind. Ken challenges Mr. Ko to a gambling match, aiming to provoke a mistake and gather intelligence while preparing for a confrontation.

During the gambling match, Mr. Ko's assassins attack Ken's house, where Rainbow, Cool, and Ngau-Ngau are present. Rainbow is placed inside a gas-filled glass tank, putting her life at risk during the chaos. Ken reveals his unique ability to read cards through a surgically implanted sensor in his fingernail.

The police, inspired by a football match where Lionel Messi scores, start a revolution against Mr. Ko’s criminal empire. Following his downfall, Mr. Ko attempts to escape but is met by Ken, who shoots cards at him in a final confrontation, eventually capturing and arresting him.

On the first day of the Lunar New Year, Ken conducts disciple rituals with Cool, signaling a moment of spiritual and martial training. During the ritual, Cool receives a mysterious call from a figure interested in taking him as a disciple, hinting at a new chapter in his journey.

The scene climaxes with a man dressed in a black suit, who walks into Ken’s place and declares himself ready to train Cool as his disciple. This man is revealed to be Ko Chun, the legendary God of Gamblers, suggesting a new mentor with immense skill and influence.
