Marshal Jim Calladine had been hunting the outlaw Cal Forden, wanted for armed robbery, land thieving and gun-running to the Indians. Then, murder was added to those crimes – with Calladine as the victim. His brother, Steve, set out on a mission of vengeance. Following Jim's trail, Steve joined a wagon train heading west, passing near to Calder Wells where Forden held sway. Steve might never have reached the town had it not been for Melanie Ridgeway, who saved his life when their wagon train came under Indian attack. But, this was only the start of his problems, and if Steve was to survive to face Forden, he was going to need all the help he could get.
