Overview:

Tien-Fu Liu, a tycoon who is well connected in politics and business, and his son, Won-Tsung Liu, have been buying and selling large amounts of illicit drugs. Cheng-Hsien Lee (a police officer of Criminal Investigation Division) is instructed by his superior officer, Yao-Wei Lee (Chief of No. 1 Team of Criminal Investigation Division), to be an undercover to investigate the illegal activities of Tien-Fu Liu and Cheng Long Group. In the police's effort to crack down on Cheng Long Group, several policemen and policewomen shed their blood; however, Cheng Long Group, with great ties in politics and business through money, is not so easy to be destroyed. In the process, Cheng-Hsien found out that Tien-Fu Liu was the person who killed his father. In the meantime, another serious crime takes place and Cheng-Hsien, who has been utterly devoted to his job, immediately engages in a battle with the criminals so as to defend justice against evil and injustice.
