The story begins with Chon Wang (played by Jackie Chan), a former Imperial Guard of China, who has become a sheriff in Carson City, Nevada. He receives news that his father, Keeper of the Imperial Seal of China, has been murdered in London. Determined to bring his father’s killer to justice, Chon travels to London to investigate.
In London, Chon reunites with his old partner Roy O’Bannon (played by Owen Wilson), who has become a struggling con artist and entertainer. Together, they embark on a quest to track down the murderer and recover the stolen Imperial Seal, which holds great significance to the Chinese Emperor.
As they search for clues, Chon and Roy encounter a series of colorful characters and get caught up in various misadventures. Along the way, they cross paths with British aristocrat Lord Rathbone (played by Aidan Gillen), who is revealed to be the mastermind behind the plot to steal the Imperial Seal.
In their quest for justice, Chon and Roy team up with Rathbone’s feisty sister, Lin (played by Fann Wong), who is also seeking revenge against her brother for betraying their family. Together, they infiltrate Rathbone’s mansion and confront him in a climactic showdown.
In the final battle, Chon and Roy face off against Rathbone and his henchmen in a thrilling and action-packed fight sequence. With their martial arts skills and quick wit, they defeat Rathbone and retrieve the stolen Imperial Seal, avenging Chon’s father’s death and restoring honor to their family.
In the end, Chon decides to return to China to continue serving as a sheriff, while Roy stays in London with Lin, embarking on a new life and leaving their days of adventuring behind them.
