Overview
Guo Cong, Chief of the Travel Inspection Division at Huayan Airport Customs in Binhai, leads officers Zhang Yu, Lü Xiaoyan, Yan Bowen, and others in holding the frontline of national security. Within the fifty-meter stretch of the customs clearance channel, they see through deception, intercept smugglers, and crack down on a series of complex cases—from illegal gene sample trafficking and drug-concealed carpets to the smuggling of precious artworks, HPV vaccines, luxury watches, antiques, and psychotropic drugs. Through relentless efforts, they overcome daunting challenges, uncover the masterminds behind the smuggling rings, and safeguard the nation's interests. These young customs officers, in this process, gain invaluable experience and forge unbreakable bonds in the line of duty.
