JJ is a high-risk prisoner, having participated in several crimes, but she was finally captured. Within the correctional facility where she is incarcerated, all contact with other inmates is prohibited, and they are kept in complete isolation most of the time to prevent riots. However, the maximum-security prison has also implemented a new rehabilitation method, or rather, a method to punish inmates more severely by confining them in small cages. JJ will be one of the first to experience this psychological shock of being locked in a small cage, and her reaction will be observed before this method is used on all the prisoners.
