A heated sporting rivalry divides Giorgio Roberti and Fausto Renzi, both capable marathon runners. After a defeat the latter contemplates abandoning competitive sports, but is convinced by Silvia Delotti, daughter of the sports organizer of the "Aurora", to return to his father's "stable". The rivalry thus also becomes sentimental between Giorgio, already in love with Silvia, and Fausto.
