Away from North Fork on a trip for the Cattleman's Association, Lucas rescues a man and is drawn into a fight with the crooked owner of a gambling establishment. Lucas goes to the Marshal for help, who seems adverse to cooperating. It soon develops however, that the Marshal is more clever than he appears on the surface, and he and Lucas startle the town and the court when they resolve the dispute and the crime with a new science known as "ballistics."
