In 1997, the Narcotics Control Bureau had not yet been established. Facing the sudden outbreak of drug crisis, the northeastern city of Halan temporarily formed an elite team. They all had their own strengths, but they knew nothing about new drugs... The young criminal police not only had to face the vicious drug trafficking groups and cunning and bizarre drug transportation methods, but also had to withstand the choice between love and law, and the test of justice and humanity. They were loyal to each other, overcame all difficulties, and created a passionate legend of punishing evil and eliminating evil.
