Six prisoners. One locked room. Zero mercy. The escape room from actual hell.
Japan in the near future. Six prisoners, male and female, in prison, who have signed a "Special Pardon Pledge" are taken to a secret room covered in concrete with no way out. They are brought to a secret room covered with concrete with no way out. There are monitors on the walls and several surveillance cameras on the ceiling. The room is lined with boxes of various sizes with locks on them. There is only one condition to pass the special pardon examination: to escape from the room by using the items in the boxes given to each person.
