Toby McLean, a reckless sports writer on a New York City newspaper, covers the Gene Tunney-Jack Dempsey heavyweight-championship fight in Philadelphia. There he meets Ann Vaughn, a feature writer for another newspaper, and they get married after a whirlwind romance. The romance begins to wane nearly as fast as it blossomed but, directly and indirectly, is salvaged by Toby's writer pal, "Shorty" Ross, and a ditsy socialite, "Puff" Randolph. Artchive footage provides shots of the Tunney-Dempsey fight, and other sports events of the era.
