Against the background of the turbulent undercurrents of two super intelligence organizations in the East and the West, Li Yunze and others unexpectedly received an infiltration mission that was related to the overall situation, but found that there was a conspiracy hidden behind it that tipped the balance of the world. As identities are exposed one by one, undercover agents are reversed, and misunderstandings and jokes come one after another, the protagonist team gradually uncovers the ultimate mystery through constant battles of wits, tit-for-tat, and even accidental collisions. They also achieve growth and self-breakthrough between mutual trust and misunderstandings, intertwining the cruelty and humor of spy wars, pathos and hope, calculations and true feelings.
