Stubbs the Zombie

Stubbs is reunited with the woman he loved when he was alive... and he eats her brain. Their son Andrew tries to kill him for revenge for everything Stubbs did, Stubbs beats him and Maggie (now a zombie) convinces him to spare Andrew. The entire town of Punchbowl is now in ruins overrun with zombies and the ever dwindling living humans. The US military nukes the city before Andrew can escape, while Stubbs and Maggie escape in time on a boat, meaning the Zombie Apocalypse has spread beyond Punchbowl. Happy ending?
