When the world last checked in with its favorite Cheeto addict, the planet had been overrun by flesh-hungry beasts, and nature had started reclaiming her territory from humankind. S.T., the intrepid crow, alongside his bloodhound-bestie Dennis, had set about saving pets that had become trapped in their homes after humanity went the way of the dodo. That is, until S.T. stumbled upon something so rare and precious that he vowed to do everything in his power to safeguard what could be humanity's last hope for survival. But in a wild world plagued by prejudiced animals, feather-raising environments, new threats so terrifying they make zombies look like baby bunnies, and a horrendous dearth of cheesy snacks, what's a crow to do?

S.T., a domesticated crow, is a bird of simple pleasures --- hanging out with his owner Big Jim, trading insults with Seattle's wild crows, and enjoying the finest food humankind has to offer: Cheetos. But when Big Jim's eyeball falls out of his head, S.T. starts to think something is not quite right. He is left with no choice but to abandon his old life and venture out into a wild and frightening new world with his trusty steed Dennis, where he suddenly discovers that the neighbors are devouring one other. Local wildlife is abuzz with rumors of Seattle's dangerous new predators. Humanity's extinction has seemingly arrived, and the only one determined to save it is a cowardly crow whose only knowledge of the world comes from TV. What could possibly go wrong?
