Anti-narcotics captain Lu Zheng and emergency doctor Su Wan met in the poisonous smoke and gunpowder on the southwest border. He defends the territory with blood as a blade, and she saves the common people with kindness. Their love grows in the crisis of life and death, but is crushed by the drug lord's conspiracy and the fate of sacrifice. After Lu Zheng fulfilled his mission with his life, Su Wan took his faith and stood alone on the front line of emergency medicine and drug control. In the endless thoughts, he continued to write the justice and affection of the border.
Intent: The poisonous fog at the border has never dissipated. The sacrifice of a hero is not the end, but a beacon for successors to move forward, demonstrating the tragedy and perseverance of "the anti-drug war will never stop".
