A film about another American fad of the 30s. Small-town bumpkin Winfred Simpson is annoyed by the attention paid to his girl, Phyllis Jenkins, by a hotshot trick cyclist, Harry St. Clair, breezing through and impressing the locals on a personal appearance tour at the town theatre. When Phyliss turns Winfred down, he hits the road to become a success at the big 6-Day bike race. He meets Clinton Hemmings and they become partners as it is a two-man event, and get practice time for the race by getting jobs as bicycle messengers. Winfred, delivering a message to St. Clair at his hotel, mistakes a voice he hears in St. Clair's room as Phyllis, gets into a fight with him and hauled off to the pokey.
