When a train carrying a Wells Fargo express car is robbed, Hardie is assigned to recover the stolen money. His efforts are handicapped by a new trigger-happy detective he is training who disapproves of Jim's methods as being too soft.
Hardie is ordered to track down the man who murdered a Wells Fargo messenger. He is helped by the driver who recognized the killer and is willing to testify. The town is wild and Hardie is surprised at the actions of several people.
Jim and his foreman, Jeb Gaine, are busy moving onto the ranch purchased from Ovie and her two lovely daughters when the Wells Fargo agent is called back to service to retrieve plates used to counterfeit bonds. Hardie learns the plates were stolen by a group of former Confederate soldiers who plan to print enough worthless bonds that the United States economy would fall into shambles.
