Our Heroes manage to finally track Murphy down. They come across a wagon train caravan of desperate survivors transporting victims of the nuclear blast to safety. Along the way they are attacked by “Blasters,” superfast zombies mutated by the radioactive fallout. Our Heroes are introduced to “Z-Weed,” an ultra-potent strain of marijuana grown in zombie compost. They go on a quest for “Batch 47,” a potential cure for the Zombie Virus.
