On his way to investigate irregularities in a bank's bookkeeping, Bat encounters a gun fight in which a man is killed by two gunmen. Bat finds himself involved with embezzlers, murderers and a new friend - a thieving dog.

Bat receives half of a cane he gave to Jane Taylor and rides to her ranch to investigate. He is forced to choose sides between her family and other ranchers and his old friend, a cattle baron intent on returning to the days of open range.
