Lin Jue’s life at university has suddenly turned into a nightmare. One night, his campus is sealed off and all students are turned into zombies—except for 13 people, including Lin Jue himself, who received a mysterious easter egg. Some sort of twisted “game” has begun. Now Lin Jue and the other twelve must survive the night in this hellhole and figure out exactly what this horror game entails. Lin Jue may be able to forge bonds with the others, including a relationship that turns more intimate, but who will end up a greater threat to him: the zombies after his flesh, or the comrades who might betray him?
