A zombie virus suddenly breaks out at Hyosan High School. Students and teachers become trapped inside the school as the infection spreads rapidly through bites. A small group of students must fight to survive, escape the building, and reach safety while the entire city outside collapses into chaos.
The virus makes infected people extremely aggressive, but some individuals show traits — they are infected yet retain some consciousness and immunity to full zombification. The series explores friendship, sacrifice, bullying, and social collapse among teenagers. HDMovies4u.SBS-All.of.Us.Are.Dead.S01.1080p.NF.WEB
