Dong stands a chance to win a Grand Slam, however, his hesitant attitude makes his teammate extremely puzzled. It turns out that after Dong’s mom died, he lived with his father, Chou Ta-Lung, whom he had never met before, and met a rally racer, Jun, who changed his life. The father and son gradually fixed their relationship due to Jun. Meanwhile, Jun was haunted by an unpleasant past. Nevertheless, the sense of guilt gave him the strength to get back to Rally. While the skeleton in the closet threatened Jun, Chou Ta-Lung made up his mind to become Jun’s co-driver to live up to Dong’s expectations and to prove himself. This unexpected decision changed the fate of the three.
