To protect family affection and fairness, he accompanies his sister to investigate suspicious aspects of the demolition compensation, tracing everything from fake signatures and old ledger books to an interest dispute involving twenty-eight households of villagers. Facing misunderstandings and heavy obstacles, Huo Zhenchuan insists on taking facts as the basis and the law as the criterion, finally uncovering the truth and helping his sister and fellow villagers safeguard their legitimate rights and interests. When a new rescue mission arrives, he puts on the old clothes mended by his sister once again, rushes to the frontline of rescue, and interprets true heroic qualities with responsibility and commitment.
