All of Us Are Dead

Bad things are happening at Hyosan High School. Some students, including Teacher Lee's son, are consistently bullied, and the school administration is turning a blind eye to it. When a student is bitten by a laboratory hamster, Teacher Lee isolates her and is suspected of kidnapping. The victim is taken to the hospital, and despite Teacher Lee's protests and requests for a quarantine, he is taken to the police station. However, the zombie virus has already spread to the school nurse and is rapidly infecting students. The few survivors must use all their skills and ingenuity to avoid being devoured by their former classmates.
