Dong stands a chance to win a Grand Slam, however, his hesitant attitude makes his teammate extremely puzzled. It turns out that since Dong's mom died, he has lived with his father, Chou Ta-lung, who he never met before, and met a rally racer, Jun, who has changed his life. The father and son gradually fix their relationship due to Jun. Meanwhile, Jun is haunted by an unpleasant past. Nevertheless, the sense of guilt gives him strength to get back to rally. While the skeleton in the closet threatens Jun, Chou Ta-lung makes up his mind to become Jun's co-driver to live up to Dong's expectation and to prove himself. This unexpected decision will change the fate of the three.
