Andy Larson, wanting to get away from the bootleg crime and corruption of prohibition in North Dakota, moves to Wolf Point, Montana, to take on an easy job as a deputy sheriff. Immediately after his arrival the sheriff and police chief are gunned down and Andy, as the new sheriff, finds this area is a hot bed of big-city mobsters, crooked cops, and lethal double crosses. Andy is not above having a drink or two himself as he devises a sting operation to pit gangs against each other, encounters a WWI flying ace bringing in bootleg booze under the wings of his plane and battles relentlessly to try to stem the flow of liquor coming through from Canada.... This is not the easy job Andy Larson was expecting.
