On the night of the Spring Festival holiday, the bar street in the city center was bustling and noisy. Hong Kong movie star Mr. Wu (played by Andy Lau) was kidnapped by Zhang Hua (played by Wang Qianyuan), a group of people pretending to be police, to an isolated suburban courtyard with guns. Mr. Wu accidentally discovered that the kidnappers had also kidnapped another hostage, Xiao Dou (played by Cai Lu). After a negotiation with Zhang Hua, Mr. Wu pulled Xiao Dou back from the brink of death. The two began a thrilling 20 hours of fighting for life and relying on each other. The police who received the report quickly organized the strongest police force, and the criminal police captain Xing Feng (played by Liu Ye) and Cao Gang (played by Wu Ruofu) jointly launched the investigation. But the cunning and arrogant kidnapper Zhang Hua has a strong anti-reconnaissance ability, and he does not follow the rules for his accomplices and hostages. He went out alone to collect the ransom with Mr. Wu's friend (played by Lin Xue). But when he got the ransom, he told his accomplices to kill the hostages by nine o'clock in the evening, regardless of whether they could get the ransom or not. After several investigations and confrontations, the police got hold of Zhang Hua's whereabouts. Xing Feng and Cao Gang cooperated precisely and captured Zhang Hua in an extremely dangerous situation. There were still two hours left before the kidnappers agreed to kill him. At nine o'clock in the evening, Xing Feng and Cao Gang teamed up again to fight with the dying Zhang Hua and found a breakthrough at the last moment, but Zhang Hua's accomplices planned to kill him early... The film is adapted from the 2004 "Wu Ruofu Kidnapping Case".
