In Old Wyoming, a gang is plundering stagecoaches of shipped currency and a crusading newspaper editor is trying to get the local marshal replaced, because of his apparent failure to catch the gang, which seems to disappear into thin air after every robbery. The situation escalates when one of the stage drivers is mortally wounded; so the marshal sends for his friends, the Range Busters, to help him catch the criminals.
Another entry in the RANGE BUSTERS series which has Corrigan, King, and Terhune rounding up a renegade gang and making the once quiet Rock River a pleasant place to live again.
