Plot
Es wakes up in a strange place, with a rabbit on their lap and no recollection of where or who they are. The rabbit introduces himself as Jackalope, and goes on to explain; Es is a prison guard, tasked with the job of managing the 10 prisoners incarcerated in the prison. Jackalope warns Es that despite what they seem, all the prisoners in MILGRAM are murderers.
By watching the music videos extracted from the prisoners' minds, Es must find out what their crimes and motivations were, and then choose whether to forgive them or not. Depends on Es' verdict, the prisoners' behavior and mindset will change in each trial.
