Zhao Yipeng (played by Donnie Yen) is an honest and upright person who keeps to himself. One day, his boss Chen Tianxiong (played by Yun Yangming) asks Zhao Yipeng to escort a large sum of five million to the bank. Unexpectedly, Zhao Yipeng encounters robbers on the way, and the money is stolen in an instant. Both Chen Tianxiong and the police believe that this is a self-directed case by Zhao Yipeng, intending to embezzle public funds, leaving Zhao Yipeng speechless. As a result, he loses his job, and his hard-earned savings are taken away by Chen Tianxiong. In his anger, Zhao Yipeng kidnaps Chen Tianxiong's daughter, Chen Qianru (played by Chingmy Yau), to extort a ransom of ten million from her father. On the day of the ransom delivery, an accident occurs, and Chen Tianxiong shifts all the blame onto Zhao Yipeng. By coincidence, Zhao Yipeng saves the endangered Chen Qianru, who listens to his account of the events and feels great sympathy for him. A series of accidents lead Chen Qianru to discover her father's greed and coldness, leaving her disappointed. Together with Zhao Yipeng, they transform into a duo of vigilantes, taking down evil.
