Jules and Fernand are waiters in a bar in Marseille. Fernand, in addition to the secret passion he feels for Antoinette, his friend's daughter, only lives for sport, which he practices as soon as his free time allows it. Here they are both engaged in the annual race of the waiters. Against all odds, Jules wins and prepares to pocket the 5,000 francs prize. But Burette, a crooked impresario, manages, thanks to one of these pirouettes of which he has the secret, to steal the jackpot from him, before leaving for Paris. Jules, in his footsteps, does the same, soon followed by Fernand. Once in the capital, repeated misunderstandings successively make Fernand pass for an automobile champion, then for a boxing ace.
