Before Jess leaves Stratton, Texas, U.S. Marshal Frank Reedy gives him an unwanted assignment. The job forces Jess to go north to the town of Loveland, Nebraska, to hunt two vicious killers, Bernie Crangle and Rueben Gideon.
Jess doesn’t want to go because it’s the time of year when it can get cold in Nebraska. Worse, the only way to get there fast enough in the hopes of getting back to southern Texas, and a warmer climate, is to get on another train. He reluctantly agrees because he owes Reedy a favor.
He makes his way on the hunt for the two vicious outlaws and seems to find trouble around every corner. The train he’s on is carrying a huge gold shipment, guarded by an old friend, Vic Pardo. There are rumors of a robbery attempt and trouble soon follows.
He finally gets to Loveland, and starts his search for the two killers there, but they are leaving a trail of dead bodies in their wake. He needs to find them before the list gets longer, but he’s hampered by another bounty hunter and a woman who seems to have an interest in the two outlaws.
After the job is finished, he heads south again, but the snow flies and the cold comes. By the time he arrives back in Stratton, another ally surprisingly shows up and Jess is not sure it’s a good sign or bad. One thing is for sure. He’ll soon find out.
Jess is on the hunt for the vicious Van McLarty and once he puts him down, he takes the body into the town of Palmdale, Texas, where he runs into a very disagreeable county sheriff and the Corker clan. It seems the Corker men think they run things around their area, including the county sheriff.
After his run-in with three of the Corker men, the leader of the group, Hagar Corker, declares war on Jess and the town of Palmdale. The county sheriff rides out of Palmdale and leaves Jess to handle the clan by himself. Lead flies and blood is spilt before a truce can be agreed upon.
After leaving Palmdale, Jess finds himself being held against his will on a moving train owned by a wealthy man by the name of John Roscoe. He offers $100,000.00 to the gunslinger who can take Jess in a duel. The train snakes its way through Texas, New Mexico Territory, Louisiana, Mississippi, Missouri, and Ohio, where Jess faces some of the deadliest gunfighters no one ever knew existed. His last challenge is with Roscoe, but Roscoe doesn’t play fair.
After teaching Roscoe a lesson, Jess heads to Stratton, Texas for a quick visit, but Reedy has a deadly job waiting for him. One that requires his special set of skills. He has to hunt down a former Texas Ranger who is hiding in a huge forest, and he’s an expert with a sniper rifle. To make matters worse, the Ranger has gone completely mad. Jess goes in, but will he come out?
Jess is on the hunt for Hank Shelly, which leads him to the spot where a stagecoach robbery took place with two men left dead on the ground. He tracks Shelly for a short while from the scene, but Shelly is covering his tracks well.
That takes him to the town of Holly, where he meets a rich rancher by the name of Orton Ruse. He quickly discovers that Shelly, who had previously worked for the rancher, robbed the stagecoach and took one hundred thousand dollars that belonged to Ruse.
Ruse offers Jess a large cash reward to hunt Shelly down and get his money back. Meanwhile, another man, who was inside the stagecoach when Shelly robbed it, decides to go after Shelly himself for the money.
Their paths cross several times and Jess is not sure if he’s a friend or foe, but time will tell as the two men hunt for the elusive Hank Shelly.
Jess’s hunt for Jon McBride leads him to a little no named town in Texas. He quickly dispenses his brand of justice and sends McBride to the hot coals of hell. As luck would have it, another killer shows up minutes before Jess leaves the town. When he finally rides out, he’s hauling two stinkers behind his packhorse.
He takes the corpses to the town of Diablo, Texas, where he must deal with some less than desirable officials. After resolving the matter, he heads for the town of Sudbury on the hunt for the next man on his list.
His hunt then takes him to Malvern, Texas, where he runs into a whole mess of trouble and a town marshal that doesn’t want him to leave. He sticks around for a few days, hoping to catch his next prey, Ben Essex, but things heat up in the town with people trying to find their fortune in the hills nearby.
Before he leaves Malvern, he receives an urgent message from an old friend from his hometown of Black Creek, Kansas. He heads there and finds himself defending the town he loves once again. He is faced with drifters, a cattle drive, and a professional gunslinger who wants him dead for the reputation.
Jess is tracking a murderous monster, Mark Milton, through the state of Texas, but he keeps slipping through his fingers and leaving a trail of dead bodies behind.
Things get more complicated when an unknown foe starts sending men to kill Jess, making his job of catching up to Milton more dangerous. As he hunts down the madman, he uncovers a plan to have him murdered, but still has no idea of who is behind it.
By the time he finally kills Milton, he has information that will take him to St. Louis, Missouri, where he finds help from some old friends. They unravel the entire plot, Jess ends it in his usual manner. He then sets out with his friends to finish a hunt for a man in New Mexico Territory.
