The Nanyang City Anti-Drug Detachment is a battlefield of life and death on one side, and an emotional whirlpool of undercurrents on the other.
Song Zixing and Jiang Zhiyue, both of whom were burdened with the bloody shadow of their childhood, gave their lives to their mission the moment they swore to become anti-narcotics police officers. He is the cold-faced undercover "Lone Star", and she is the logical "Qing Zhi". When tracking down the new nano-drug code-named "X-7", the two lonely souls warm each other on the edge of life and death, using trust as the blade to pierce the drug lord's layers of disguise.
The secondary CPs An Zhiyu and Mu Yunxi are the light and shadow of the team. They are immersed in the ocean of technology, and they are also healing the past in each other's company.
This is not only a battle between good and evil, but also a dark night starry song about redemption and faith. When the truth emerges, can they keep their original vows?
Purpose: Unsung heroes on the front lines of anti-drugs
