Sandra Morrison was a new investigator for the state, fresh out of the academy. Because she would not be recognized, she was chosen to go undercover to investigate rumors that the female inmates of Stonebrook State Hospital for the Criminally Insane were being abused.

Once inside, posing as an inmate with the promise that head of the state Division of Criminal Investigations would ensure she is released after a month gathering evidence, she finds that the rumors grossly understate the conditions the female inmates have to endure.

Harsh conditions and daily suffering prevails. Punishments are dealt out for any reason or no reason. Instead of being a source of healing care, the institute is a hell pit of degradation and abuse. Sandy endures whippings and worse at the hands of an ingeniously cruel couple of administrators. When the time comes for her to be rescued so that she can make her report, there is a little surprise awaiting her. Sandy faces a lifetime of torment with no chance of release, enough to drive her truly insane!
