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.

While his stage makes a stop, Bat is arrested, charged with possession of a gun and assessed a staggering fine. When Bat learns that the local judge runs the town as a personal fiefdom, he decides to change things when a man faces hanging.
