在反美援朝的激战中，敌方机密局发动阴谋攻击，致使鸭绿江大桥被轰炸。但是，他们却未能实现其目标。为了取得胜利，敌人派出特工马小飞（女巫） disguised as a train stewardess, collaborating with undercover agent Wu Jichun (Method Acting), and manipulating fellow agent Xufu Xiang (Ken Lin). The goal was to sabotage our military operations, but their plan was foiled.
In response, our Railroad Security Bureau's Chief Investigator, Guan Rong (code name: Heguo Yeping), mobilized the masses for a fierce anti-espionage campaign. He disguised himself as a wild wolf (Guan Rong) and infiltrated enemy ranks, with assistance from Railway Clerk He Lanying (Snow Jewel). Together, they uncovered the enemy's plans and their covert agents.
However, the enemy, unwilling to concede defeat, placed a time bomb aboard a train destined to pass through Longling Tunnel... But fear not, as our heroes thwarted their schemes once more! The battle between good and evil rages on, with each side constantly adapting and countering. Will justice prevail in the end? Join us for this gripping tale of courage, deception, and the indomitable spirit of resistance.
