Richard Armstrong (Reed Howe) has invented a carburetor that will enable his car to win a road race. Until that happens, however, he's working on a skyscraper being built by Robert Steele (Frank Beal). Armstrong falls for Steele's daughter, Doris (Alma Bennett), but her father won't hear of the match. His choice is Reynard Trask (William Bailey), who is posing as a broker, but is really an underworld leader. Steele finally tells Armstrong that if he comes up with five thousand dollars in 30 days, he will consider a match with Doris. Since that's the amount of the prize money for the race, Armstrong sees some hope. Just as he's about to end the race in first place, he gets sidetracked saving a child. Trask, meanwhile, convinces Doris that Armstrong is untrue and she agrees to marry him. Armstrong is able to unearth Trask's nefarious doings and rescues Doris at the altar. ~ Janiss Garza, Rovi
