Deadly Infiltration

In an international bidding process, the core parameters of the "Tianxuan" project of Hudong Guotong Group's Star Shield were mysteriously leaked. Behind the huge losses is a hidden wound torn within the group. Liu Jiang, Director of the Investigation Division of the Provincial National Security Bureau, was ordered to attack and formed a temporary partner with Xiao Jin, Director of the Group's Secrecy Division. As the investigation gradually deepened, they discovered that this was not a simple commercial theft. A hidden overseas undercurrent was quietly infiltrating by exploiting the hidden gaps in human nature. New technological talents who have returned from studying abroad, technical backbones who are in trouble, decadent and frustrated middle-level cadres, high-ranking technical authorities, leadership secretaries who are cautious in words and deeds, seemingly ordinary cleaning staff... Everyone seems to be dragged into a huge puzzle by invisible hands. When the investigation approached the core, Xiao Jin was shocked to find that the clues pointed to the corner of her most familiar life. When family affection collides with national law, when personal grudges trigger a crisis, and on the edge of the cliff between national security and personal emotions, Xiao Jin must make a choice. This war without gunpowder has never been so close to everyone's life. Under the calm waters, who is the real "shield breaker"? And who can build the last impenetrable line of defense?
