Internal Affair (1994)

The Chief Inspector Li Tiezhu took over the investigation of a case involving police officers colluding with the underworld. The target person was Huang Zhenxiong, the head of the Serious Case Team, and a group of his agents. Xiong has solved many cases due to the help of the underworld, but also received the benefits of the underworld and violated the law and discipline. Li Tiezhu wants to collect the criminal evidence of Xiong and others. However, because Xiong is also a capable police officer who is good at hiding the criminal evidence to escape the punishment of the law, Li cannot bring Xiong to the law for a time. Later, a new captain named Chang joined Xiong. Chang was an honest police officer. Xiong wanted to buy the room and failed. Li also took the opportunity to use Chang to collect evidence of Xiong's crime to arrest Xiong, who was afraid of committing suicide.
