A bus suddenly breaks down with brake failure. The ex-wife Lu Qiuwan uses her dispatcher permissions and the lives of 57 passengers on board to blackmail Shen Dashan into being publicly humiliated. To protect everyone on the bus, Shen Dashan endures the humiliation and successfully escapes danger relying on his superb driving skills. In subsequent investigations, an old case of the older generation and the dark secrets of the passenger transport industry surface, and he discovers that his ex-wife's father is actually the true culprit who killed his father. Shen Dashan rises to the challenge, fights against dark and evil forces and industry lawbreakers, gradually uncovers all the truth, and brings criminals like Lu Zhentian and Zhao Erye to justice. He declines generous treatments, sticks to the original aspiration of a bus driver, holds the steering wheel tightly, and rushes toward a new life facing the morning sun.
