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.
