While investigating a tanker explosion case, news reporter Hau Man-wan (David Siu) suspects it as scheme for Au Chi-ho's (Kenneth Tsang) consortium to deceive insurance money. Man-wan uses his relationship with Au's daughter, Man-ching (Frances Lau), to get close to Au, hoping to find out the truth. Au is fiercely ambitious and in order for him to expand his influence, he resorts to ruses to annex the force of his opponents and uses Man-wan to gather criminal evidence to put his opponents in jail.
At this time, Man-wan's good friend, police inspector Tse Kwok-tung (Donnie Yen), whose girlfriend, Candy, was recently murdered, suspects the culprit behind this case to be Au's underling, Lee Long (Francis Ng). Kwok-tung decides to closely investigate this with his old partner, sergeant Lee Fan (Ng Man-tat). However, Kwok-tung was framed while investigating and was transferred to another department, with female inspector Hung Wai-ling (Kitty Lai) takes over his duties. Wai-ling is Man-wan's girlfriend who opposes her boyfriend to investigate Au, while also prevents Fan from helping Kwok-tung. As a result, Fan is highly dissatisfied with his new superior and often gets into conflicts with her, giving little development the investigation. Later, Wan-wan decides to put his life at risk and go undercover into Au's organization in order to find out the truth, hoping to assist Kwok-tung and Fan on the investigation.
