Synopsis: Why's that straight-talkin', straight-shootin' Americano saddling up with a south-of-the-border gang? Has rodeo cowboy John Bishop (John Wayne) joined the Brotherhood of Death? You got that right, partner - but he's there just long enough to foil the gang's silver-mine raid and rescue a youth it holds captive.
In the penultimate film he made for Warner Bros. during a one-year burst of out-West action in the early '30s, Wayne does some mighty fancy knife throwing and quick drawing to win his way into the bandit gang. And there's plenty more action, too: a stagecoach race, a runaway buckboard, a barroom brawl and a bullet-zinging shootout. You'll find a heap o' Western adventure Somewhere in Sonora.
