The Racing Fool.

Racing driver Jack Harlowe falls in love with Helen Drake, the daughter of his father's rival automobile manufacturer. Having promised his father to drive in the big race, Howes must refuse the girl's request that he drive for her father, but when he learns that another man (who has his eye on the girl) plans to drive for her father and throw the race, Howes receives parental permission to win the race for the rival.
