In a bid to eliminate the person threatening to expose him, Paul Varlo contaminates the water supply, inadvertently triggering a zombie apocalypse. These aren’t your typical zombies; they’re quicker, more vicious, and disturbingly, they’re armed. As the town is overrun by these swift, gun-toting undead, a group of survivors attempts to flee to Chicago for safety. At the same time, Jake and his girlfriend Laura are en route to Spring Grove to deliver a valuable heirloom to Varlo and claim their $2 million reward. Upon arrival, they find a deserted town, its streets stained with blood. Can the group withstand the horror that has engulfed them? Will Jake and Laura secure their $2 million? And will the zombies eventually run out of ammunition?
