Intro. The School in Ruins Seoul high school, once a place of learning and laughter, was now hell on earth. An unknown virus had turned most of the students and teachers into bloodthirsty zombies. Min-Soo and Jae-Hyun, two inseparable friends, were trapped in the classroom with a group of classmates. Panic and fear had taken over them, but they knew they had to stick together to survive. The hall was on the third floor, and the only exit was blocked by a horde of zombies screaming and clawing at the door. The boys had managed to keep them at bay with a metal bar, but they knew it wouldn't last long.
