Texas Rangers Are About to Take on A New Mission: Zombie Extermination In the small town of Alpine, Texas, a freak big-rig accident unleashes a mysterious toxic gas.

Armed to the teeth, they're not about to let an army of undead monsters stand in their way. But all their firepower might be no match for mutant fangs. Their success would contain a doomsday plague of zombies. And failure? Too horrible to imagine...
