Watch Cowboys vs. Zombies

Civilization has been ravaged by a nuclear war and the undead have risen to attack what is left of humanity. Shadrach, one of the survivors, watched his life burn to the ground after a devastating attack left him mortally wounded. In his dying breath he sold his soul, becoming eternally enslaved to the forces of Hell. Tormented for centuries, he now has a chance to regain his soul, but to do so he must save an entire town from the living dead while battling his own demons at the same time.
