William Colt MacDonald

Rancher Tim Clark borrows money from Bob Russell, who then rustles Clark's cattle so he will be unable to repay the money. Thus Russell is able to cheat Clark out of his ranch. Clark becomes a prospector for silver and ultimately comes to settle accounts with Russell and crooked deputy Bendix.

The Three Mesquiteers are forced to track down a train robbery ring after some of the gang hijack their truck for a getaway and the police conclude they are part of the gang, an identification which is just fine with the gang's nameless chief.
