On the border anti-drug frontline, the enthusiastic and outgoing rookie drug police officer Zhu Ping'an, like a reckless and warm little sun, crashed into the perennially frozen world of senior field officer Jiang Yuan.
Jiang Yuan has always been cold-faced and taciturn, acting calmly. He has been walking on the edge of life and death all year round, and has long been accustomed to shouldering the darkness and danger alone; Zhu Ping'an uses the unique enthusiasm and tenacity of young people to knock on the other person's locked heart little by little with tenderness.
They went undercover together, walked through the dense miasma forest, faced the drug dealer's knife, fought side by side on the tip of the knife, and supported each other in the smoke and danger.
There is no vigorous sadomasochism, only the tacit companionship of life and death; they are walking side by side day and night, and they are each other's only destination in the dark road ahead.
Meeting each other in the dark night and staying together during the long anti-drug journey, the two originally lonely hearts eventually became the most stable "nano effect" for each other - a subtle closeness and a lifelong bond.
Mission: Perseverance and growth, two-way redemption, patriotism
