When a sudden zombie apocalypse erupts across the metropolitan area, high school student Mia risks her life to shield a stranger, only for the coward to stab her and leave her bleeding among the undead. As hordes close in, a regal figure with glowing crimson eyes parts the infected mob with a single gesture. To Mia's astonishment, the fearsome Zombie King is Damian, the quiet boy who harbored an unrequited crush on her for years.
Carrying her into his opulent subterranean citadel, Damian orders the infected to treat Mia like royalty. Living with his civilized, aristocratic undead family who politely offer her hospitality, Mia gradually overcomes her horror. As surviving military factions launch an assault to exterminate the infected, Mia must choose between human betrayers and the devoted monster who saved her soul.
