When the zombie apocalypse strikes, Anya, a girl with severe social anxiety, deliberately lets herself get infected to escape the pressures of survival and forced socializing. Surprisingly, she retains her full human consciousness, becoming a physically weak but kind-hearted zombie.
Packing her backpack, she embarks on a journey south to find her family.
Along the way, Anya secretly saves human survivors, eventually forming an unlikely alliance with Leon, a highly-evolved zombie and former special ops soldier, Zane, a formidable human warrior, Mia, an eccentric virologist, and Bruce, a terrifyingly powerful mutated zombie dog. Together, they navigate the wasteland and reach a southern military bunker.
There, Anya discovers the tragic truth that her parents were murdered by humans, not zombies. Furthermore, she uncovers the sinister plot of Dr. Victor, who plans to weaponize Anya's unique brainwaves to command a mindless zombie army and become a wasteland dictator. In a desperate final battle, Anya unleashes a devastating mental pressure ability, destroying Victor's control devices and defeating him. Rejecting the role of a ruler, Anya negotiates a fragile peace with humanity before hitting the road again with Leon and Bruce, seeking a free, undisturbed home for zombies.
