When a legendary agent who was declared "dead" by his motherland for seven years reappears as an enemy "surrender", what he brings is not only a secret that can subvert the world structure, but also an ultimate scam that tests all humanity and beliefs.
In 2024, a global intelligence operation codenamed "Through the Looking Glass" was quietly launched. The "Xuanwu" team, an outcast team of five fringe agents burdened with "historical issues", was ordered to sneak into the "Ivory Tower" of the overseas financial center and seize the quantum cryptography device that can influence the strategic balance of great powers - the "black box".
Captain Chen Jin, who was publicly "executed" seven years ago for failing in a mission, has returned with a lot of mysteries. Every step he takes is a tightrope between betrayal and loyalty. The team members each have their own unique skills and agendas: some want to get rid of their crimes and make meritorious deeds, some work hard for money, and some just seek the truth.
When they were about to reach their target after going through all the hardships, they unexpectedly discovered that the "black box" itself was a bait. The real trap points directly to the conspiracy that caused Chen Jin's "death" seven years ago. When trust breaks down and guns are turned against each other, they must find a way out for themselves in a chess game that has already been set for them to lose.
