Description：In 1962, the mainland was in a period of economic hardship. Wu Guohao (played by Ray Lui), a Shantou youth who fled to Hong Kong with the refugee tide, was unwilling to be bullied by the gang, so he joined the gang leader Fei Bo (played by Zheng Zeshi). After several desperate bloody battles, he was reused by Fei Bo, established his position in the gang, and his power grew. Feeling threatened, Fei Bo set up a trap to have Wu Guohao hunted down by drug lords. Although he did not kill him, he also crippled one of his legs. However, he himself was eventually framed by the other party and thrown into prison. Relying on the position of Chief Inspector Lei, Wu Guohao took over all of Fei Bo's territories and became the head of the four major gang families. Because he was willing to pay the police who served him to buy the position of inspector, the police station became his umbrella for drug trafficking. However, with the approach of 1973 (the establishment of the Independent Commission Against Corruption in Hong Kong), and his arrogance due to his high position and power led to his desertion by his friends and relatives, he became a hero in the underworld.
