Slocum stops a dirty railroad gang dead in their tracks...

The Big Three are running a railroad on stolen money. Slocum's money. Plus one of their bunch has made a widow out of the best looking woman in town. She wants her husband's killer so bad she's sworn to give herself to the man who kills him. For Slocum, putting a bullet in the backshooting polecat would be a pleasure. So would collecting the reward.
