Set in the 2021 city of Jinhai, China, a game called "Agent Mission" is becoming popular among young people. This game seems to be a form of entertainment, but in fact, the foreign intelligence organization "Night Mist" uses the gamers to secretly carry out espionage activities in unknown situations, and takes the opportunity to develop usable spies among players, and the evil seeds of the game are quietly spreading in Jinhai City.
Gao Tianyang (played by Han Geng), the chief of the reconnaissance section of the Jinhai City National Security Bureau, is smart and decisive, dares to take responsibility, and is an elite agent of the National Security Bureau. He cooperates with Wu Xi, an intelligence officer lurking in the agent game, to investigate a theft of a lab secret.
Huang Zicheng (played by Wei Daxun), Gao Tianyang's younger brother, is a young man who loves games. He unknowingly falls into the secret agent game and becomes the target of "Night Mist". With the help of Gao Tianyang and Wu Xi, he escapes danger and becomes an informant for the NSA with his rich experience in agent games.
Yao Yao (played by Li Yitong), Huang Zicheng's partner in the game, is a beautiful and mysterious girl. She and Huang Zicheng spent a thrilling game journey together, and the two gradually fell in love. However, she is the bait sent by "Night Mist" to win over Huang Zicheng, and her true identity and purpose put Huang Zicheng in a dilemma.
Wu Xi (played by Zhou Fang), an intelligence officer in the agent game sent by the National Security Bureau, has a deep friendship and tacit understanding with Gao Tianyang. She is a smart and brave female agent who dares to love and hate, and she not only has to fight wits and courage with "Night Mist" in the game, but also faces her complicated feelings for Gao Tianyang.
Gao Tianyang and Wu Xi discover the location of the headquarters of "Night Mist" and decide to personally go and destroy it. However, during the operation, they were ambushed by the "night fog" and fell into crisis. Gao Tianyang did not hesitate to sacrifice himself in order to protect Wu Xi. Wu Xi was grief-stricken, but found that Gao Tianyang had left a clue.
Huang Zicheng and Yao Yao are captured by the "night fog" and forced to participate in a deadly game. They must complete a series of dangerous missions within the allotted time or be killed. Huang Zicheng and Yao Yao supported each other and bravely faced challenges. In the final level, they discover a shocking secret.
Gao Tianyang and Wu Xi, other agents of the UN Security Bureau, launched a general attack. They succeeded in destroying the base of the "Night Mist", disrupting their plans and arresting their leader. However, in the joy of victory, they also paid a heavy price.
"Agent Mission" not only shows the spirit of national security personnel who sacrifice to maintain national security, but also shows the conflicts and choices of human nature in the game and reality.
