Call from the Abyss: Code Name Mole

In 198x, East Berlin. I am Jiang An, an external operative for our security service. While carrying out a recruitment mission, I watch helplessly as my informant is executed in the street. Then I fall into a perfect trap, branded a “traitor” and hunted by my own agency. Meanwhile, Shen Suwen, the headquarters' chief analyst, discovers a paradox in a top-secret intelligence report supposedly intercepted by the “Abyss Project” (the Berlin Tunnel): a Soviet expert who should have died in a car crash three years ago has “come back to life” in the message and signed his name. She is convinced that the intelligence gold mine we have so proudly relied on has long been infiltrated, turned into a “false abyss” that transmits nothing but disinformation in one direction. Her doubts make her a target of an internal purge. Two “traitors” with their backs to the wall, one fleeing for his life on the streets of Berlin, the other maneuvering inside headquarters, decide to join forces and use every means at their disposal, with no limits, to uncover the “mole” buried deep in the heart of our organization. But as they draw ever closer to the truth, they discover that this is more than just a deception. It is the ultimate trial of everyone's humanity, loyalty, and faith.
