Chief Inspector Fei Wen of the West Kowloon Police Station in Hong Kong has just solved a bank robbery case and is about to be promoted to superintendent, becoming a rising star in the police force. At this time, Eli Lewiston, a Chinese-American who had inextricable ties with the CIA and NSA, led a group of mercenaries to Hong Kong, robbed Hong Kong's largest Chinese bank, and hijacked all employees and customers in the bank. After creating a big explosion in downtown Hong Kong, he asked to negotiate with Chief Inspector Fei Wenzhi by name. The various provocative behaviors of the gang leader Eli are intended to reverse Hong Kong's situation, making the Hong Kong police stand ready and the whole city on alert. Chief Inspector Fei Wen, who was on vacation, had to take orders in the face of danger and rushed to the scene to deal with the gangsters. The gangster Eli frequently plays intellectual games with the police. The police and criminals began to battle wits and courage, and a big battle was inevitable. In the process of the desperate struggle between the two sides, various conspiracies and secrets have also surfaced.
