A shocking thriller inspired by the true stories of a male prison officer in a women's prison...

Prison Officer Jim Dalton works on the male side of HMP Peterborough. It's a dangerous place, fuelled by testosterone-driven violence, but he has the prisoners' respect. When Dalton is transferred to the female side of the prison, his next shift is so easy he can't believe that the officers over there get paid the same wages.

When Dalton is assigned to the young offenders' wing, dealing with female prisoners no longer seems so simple, and in Billie he fears he may have met his match. As Billie starts to turn the screw, Dalton faces losing everything...
