This madcap comedy concerns a bicycle race from Paris to San Remo at the turn of the century. Duroc (Bourvil) has invented a bicycle with a new and improved coasting feature. He is forced to try out his new invention when he flees a bill collector who tries to impound his bicycle. He unintentionally ends up in a bicycle race and is soon followed by the collector, his own wife, and an oily, mustachioed villain. The villain pulls out all the dirty tricks from his bag to try and defeat the determined Duroc. When the bill collector sees the effectiveness of Duroc's invention, he conspires to fall in with the wealthy patron who financed the new bicycle. The race is full of twists and turns, treachery and humorous sight gags, giving the popular French comedian Bourvil a full canvass on which to display his comic talents.
