Wang Linfeng, a former border guard, ran an auto repair shop after retiring due to an injury and was accidentally involved in a transnational drug trafficking case. Su Qing, a female police officer from the city's anti-drug detachment, came to ask for help, and the two worked together to sneak into the drug trafficking network. As the investigation deepened, they discovered that there was a huge protective umbrella hidden behind it. Lin Feng relied on his special operations experience and Su Qing's courage and agility to start a life-or-death contest in the urban jungle. From the hidden compartment of the auto repair shop to the rainy night pursuit at the border, an anti-drug storm swept across the city. The eagle in the snowy land of the past is now a sharp sword in the city, vowing to cleanse the undercurrent with its blood.
