In 1934, Harbin was starving to death. The two siblings, Jiang Xue and Jiang Han, were on their way to escape. They were rescued by the heroic Han Zhihong. Later, they encountered bandits. The three of them were separated from each other, and there was no news.
In 1944, Jiang Xue changed his identity and became the chief of the Harbin Secret Service. One day, she received news about the mob that "killed" Han Zhihong. When she arrived, she saw a small patrolman covered in blood fighting desperately with the mob, but she was surprised to find that he was Han Zhihong. When Jiang Xue called Zhihong, "little patrolman" Han Zhiyuan realized that she recognized him as his long-lost twin brother.
Surprised, Jiang Xue brought Han Zhiyuan back and sincerely invited him to join the Secret Service. With the permission of the organization, Han Zhiyuan decided to take risks and make mistakes, and infiltrated the Secret Service Section as Han Zhihong.
But is it really that easy to sneak into the enemy's heart smoothly? Who is scheming behind the scenes at so many critical junctures? What kind of secret does this ruthless Section Chief Jiang have?
When everything was proceeding in an orderly manner as planned, someone in the police department saw a person similar to Han Zhiyuan appearing on the streets of Harbin...
