The story is set in an urban country in the near future. The first intelligence agency has formed a super stealth team to face infiltration and threats from international forces. Captain Chen Zhiyuan led Shen Yanyan, Lin Yan, Aaliyah and others to solve a dangerous espionage case. From "internal plague" to "external storm", they experienced brotherhood, love-hate entanglements, crises of faith, and tests of loyalty. The true identity of the mastermind behind the scenes, the "King of Spies," was finally revealed. At the same time, each member of the team also found their own direction in the humorous, dangerous battle and growth.
