As described in a film magazine review,[2] Jack Reese, superintendent at Corbin Motors, is in love with Rita Corbin. His rival is managing director Ray Barton, who succeeds in having Jack fired. Jack and his pal Marcel Dejeans have invented a new carburetor, which they believe will work wonders in making a car win a race. The model carburetor is stolen but recovered by the chums. On the day of the big race, foul play prevents Jack and Marcel from appearing at the racetrack in time to compete. Rita shows her pluck by taking her lovers place and driving the car to victory. Jack becomes friends with Rita's father and wins her affection.
