A group of outlaws posing as Southern sympathizers and led secretly by freight-line owner Jim Maroon are raiding stagecoaches, and this is a threat to the Union communications. Grif Holbrook, a trouble-shooter for the Butterfield Stage Line, and Union man Barney Broderick team up to try and put a stop to the activity, when they aren't fighting over the charms of Kate Crocker.
