The drug market has been divided into four parts for a long time, but since Dizang and the Mexican drug lords have expanded their power across borders, coupled with a series of black-eating-black actions, the drug world has become turbulent. On the other hand, Yu Shuntian, a philanthropist and financial tycoon who hates drugs because he witnessed his father being destroyed by drugs as a child, is offering a reward of 100 million to eliminate the largest drug dealer in Hong Kong, which has caused an uproar in society. Police officer Lin Zhengfeng was committed to collecting evidence and arresting Dizang, but the drug dealer's personal safety was threatened by the huge reward. He felt helpless when performing the task of protecting the drug dealer, but was tempted by Yu Shuntian's offer and fell into a psychological struggle between black and white, good and evil. It turns out that Yu Shuntian and Dizang have an unspeakable relationship in the same school, and a showdown between heaven and earth is about to break out.
