Based on the 'Prison Diary' series from the YouTube channel Jjaltoon.
About
A zombie virus has swept the globe, and a group of inmates must survive among the infected within the prison walls. Except for the Deputy Warden, the characters share a single cell. Since cell doors cannot be locked from the inside, they never know when a door might swing open. They must remain silent whenever zombies are roaming the hallways.
