1. A trio of brutes ambush Jonah Hex and prepare to hang him from a tree tied to his horse. They want revenge upon Hex for killing their sister. But an old timer named Slow Go Smith appears and shoots the brothers down and frees Hex. Slow Go is a bounty hunter and is preparing to take the brothers to Mud Creek so he can cash in the reward. He cuts their heads off to make transportation (and proof of identity) easier. Jonah decides to come with him. When Jonah and Slow Go arrive in Mud Creek, they find a con artist offering to snap photographs of people standing next to the corpses of dead famous outlaws for a nickel. The problem being - none of the outlaws he features are in fact the genuine article. Jonah and Slow Go rent a room for the night, but Jonah kicks Slow Go into the barn because of his loud snoring. Inside the barn are the bodies of the Price Gang, another notorious gang of outlaws. Slow Go tries to fall asleep, but is awakened when he hears a noise coming from nearby. The body of one of the Price Brothers is standing upright holding a six-gun. Jonah awakens to the report of shots being fired, coming from the barn. He leaps out of his window to investigate the issue.
2. Except for the zombie infestation, folks in Mud Creek, Texas, were getting pretty bored, so it's a good thing Jonah Hex wandered into town. Nothing like a good hanging to perk things up.
3. Having narrowly escaped the hangman's noose, Hex sets out with a dead friend to learn the secret of the Mojo Man's travelling freak show.
4. Doc "Cross" Williams has captured Jonah Hex and trapped him inside of a barrel. He reveals that he has spent many years studying voodoo mysticism and has even succeeded in resurrecting the body of celebrity lawman, Wild Bill Hickok. He forces Hex to consume copious amounts of his special "zombie brew", promising that after sufficient pickling, Hex will become a mindless slave, just like Hickok. But Jonah has a pretty sturdy constitution and breaks free of the barrel. He leaps off of a cliff into the river and eventually washes up on shore, where a father and son find his body and take him in. After being nursed back to health, Hex says his goodbye and gets back onto the trail (he borrows a horse from the family). His travels eventually bring him to New Mexico where he finds a tribe of savage Chiricahua Apaches fighting against a troupe of retired army soldiers. Hex enters the fray and tries to help the soldiers. After a quick flurry of gunshots, he realizes that at the center of the fight is Cross Williams and his traveling freak show.
5. In an unlikely change of events, Hex is now forced to fight alongside Doc "Cross" Williams, the undead Wild Bill Hickok and several retired army soldiers against a raiding party of violent Chiricahua Apaches. Hex befriends one of the soldiers and the two stage their own retreat firing at advancing Apaches. But as day turns into night, the soldier begins to succumb to the infection that had set in from an Apache's arrow. Unwilling to become a play toy of the Chiricahua, the soldier takes his own life. Taking the Sarge's horse, Hex doubles back towards the initial battle scene. He finds that Doc Williams has set up camp in the hills. Shortage of food has even prompted him to kill, cook and eat, Ramona – the fat lady of his traveling show. Hex tells Cross that the Apaches are going to see his campfire and come looking for him. Then they will take their time in torturing and slaughtering him. Williams orders Wild Bill to finish Jonah off, but Hex outmaneuvers the zombie and blasts the cap of Hickok's skull clean off. Williams begins to get scared, and pleads with Jonah to save him. Jonah shoots him once in each knee, and leaves him for the Apaches to find.
