As a railroad agent, Concannon's job was to stamp out the vermin who terrorized innocent passengers. He was as quick with his temper as he was with a gun, and that's why they sent him in to recover the $100,000 looted from a westbound train. As dangerous as the assignment was, Concannon was happy to oblige. He had a score to settle. His best friend had been riding shotgun when the outlaws raided the train. They took the money and left his friend's bleeding body to rot in the sun. Concannon swore he'd fill their sorry hides with lead--even if it meant walking into his own grave.
