The protagonist Chen Mo is a top military agent who specializes in "character implantation" and "perfect disguise". He relies on his super memory and profound psychological analysis to imitate who he is. But his golden finger is also his original sin - in order to complete the task, he must completely "live" the person he replaced. He took over the identity of Zhou Wei, the special commissioner in Yan'an. He must perform in front of comrades who are familiar with him and are wary of him. During the performance, he was constantly impacted by the remaining memory fragments and beliefs of the special correspondent, and gradually he could not tell whether he was "Zhao" or "Zhou Wei".
