A grassroots food delivery worker loses his job, reputation, love, and health because he saves someone, yet he never regrets or bows his head. The rescued person's family members are top group board chairmen, searching the whole city for their benefactor; rumormongers, snobs, and the corrupt are successively exposed and punished. Wang Qiang rises from a delivery worker to a group executive, and promotes the establishment of the "Dawn Fund", so that good people are no longer disheartened.
