The U.S. Cavalry at Fort Bowie contracts with Bat for a herd of 55 horses. When his herd is stolen and his men all killed or wounded, Bat determines to recapture his herd and bring the killers to justice but it requires some trickery.

After Bat's good friend and railroad tycoon Hugh Blaine is conned in a complex land and cattle swindle, Blaine hires Bat to get his money back and bring the crooks to justice. However, Bat ends up digging his own grave.

When a man Bat staked to search for the Lost Dutchman's Mine disappears, Bat buys a map from a too agreeable bartender and sets off in pursuit. Bat soon learns that his friend is but one of many miners who have recently vanished.

In response to an urgent telegram offering a large salary, Bat rides to a remote Texas ranch where he is to drive a herd of 2000 cattle to Abilene. As he arrives he finds that the Grant family believes he's a hired killer and pays for it.

Bat is called upon by the daughter of an old friend to investigate his murder in Jackson Hole, Wyoming. The family runs a freight and stage line there but the drivers are being killed for some reason and the line is nearly bankrupt.
