Paladin is hired by Henry Ritchie, the leading citizen of the town of Ashley to stop a dam building project financed by Central City and an engineer named Mike O'Hare. The dam will cost Ashley its water supply. Other less sophisticated gunslingers are also vying for the job. Paladin's first attempt to stop the project is a simple act of sabotage that is not direct enough for Ritchie who wants O'Hare stopped by any means necessary. Paladin soon comes to realize that O'Hare is not the unreasonable man he was led to believe he is and that he could be working for the wrong side.
