Gunslinger Jonah Hex is appointed by President Ulysses Grant to track down terrorist Quentin Turnbull, a former Confederate officer determined on unleashing hell on earth. Jonah not only secures freedom by accepting this task, he also gets revenge on the man who slayed his wife and child.

Four criminals attempt the unthinkable -- ransoming the corpse of a dead child back to the family. But things take an even darker turn when they find an old spirit board at the cabin they are using for a hide-out.
