Synopsis by Janiss Garza
It seems like the main purpose of this film was to show that cowboy star Tom Mix could perform stunts that didn't require a horse and saddle. There's a lot of action, but not much plot to speak of. Billy Porter (Mix) sells his ranch and travels to San Francisco to try his hand in the business world. But he's barely off the ferryboat before he gets waylaid by a little newsboy (Georgie Stone) and the boy's pugilist father, "Knockout" McClusky (L.C. Shumway). Porter trains Knockout for his next bout, but the enemy camp drugs the fighter in hopes that the money will be forfeited. But Porter gets in the ring himself and delivers his own knock-out punch. As if that isn't enough, then Porter goes on to meet his own father for the first time and winds up in an auto race. He wins that too. And just so Mix fans aren't disappointed, he does whip up a few horse tricks which save the inevitable love interest (Eva Novak) who somehow fits into the picture.
