Alan Mancuso and his friends Mort, Steve, and Chauncey partake in the marijuana laden adventures at the Mancuso residence. While battling the usual case of the munchies, Chauncey stumbles upon an ancient sandwich, that wets his appetite. After devouring the clearly expired treat Chauncey transforms into a brain craving, gargling zombie and begins to attack his fellow friends and sparking the biggest zombie outbreak this side of Canada. Aided by his neighbor Roger, Roger's really cool friend Lembeck and the kindly Mrs. Benevitti, Alan does all that he can to fight the zombies and return the neighborhood to it's original order. After they're initial assault on the zombies fails, Roger takes off leaving Alan to run cowardly through the neighborhood and watch in horror as everyone on his block is devoured by zombies. After finding solace at Mrs. Benevitti's place, Alan waits out his final moments. Just as all hope is lost, Roger returns loaded with bullets, a big ego, and his friend Lembeck. The three of them join up and take back the neighborhood, leaving no zombie walking free.
