Guan Yuming (Jackie Chan) and his daughter Xiaofan (Leung Pui-shi) live together in London, England. Guan Yuming runs a small restaurant and honestly relies on hard work to support his family. He has never thought of overstepping the law or morality. However, God does not favor this kind man. In a terrorist attack, Xiaofan unfortunately became one of the victims. In addition to the death of his daughter, what Guan Yuming cannot accept is the contempt and inaction of the British government on the incident. Senior government official Lyme (Pierce Brosnan) appeared in Guan Yuming's field of vision. He firmly believed that Lyme was inseparable from the terrorist organization and the truth of the incident. Since the law and justice cannot give Guan Yuming justice, Guan Yuming decided to use his own power to avenge his daughter.
