Cannonball McKay is a remarkably resourceful woman who operates the Boone County Wells Fargo stage franchise. Collins, the station master, objects that she has hired crippled ex-con Clem Jones and won't allow her to carry the latest gold shipment because of a recent rash of stage robberies in the territory. The respected Dr. Tate, whose gang is actually behind the robberies, kills Collins and frames Jones as the murderer. The Ranger exposes Tate and forces him to confess when one of his men tries to blow up the town's jail. A now exonerated Jones is actually revealed to be Cannonball's husband.
