A villainous saloon keeper plots to take over Bat's bank by preventing the gold bars the bank needs to back its gold certificates from getting through and then provoking a run on the bank by its frightened depositors.

When gunslingers employed by Sam Shanks terrorize the small New Mexico town of Eden, Bat is drafted to serve as a special prosecutor when one of Shank's men is to be tried for murder and the expected result is a not guilty verdict.
