A prisoner is found dead in his cell and his death is regarded as suspicious. A riot follows and virtually destroys the prison, after two 'lifers' were questioned about the death. Helen Hewitt, who is deputy Governor of a female prison, is requested to become part of an investigation team looking into the mysterious death. Helen is offered the job of the Governor of the prison when the current governor is sacked. She uncovers cover-ups and she strives harder to get the truth.
