Tucked away in the Yorkshire Dales is a women's corrective institution where tight uniforms and catspats are the order of the day, the first often shredded by the second! Angarad Stark and Habren Gaunt are orphaned twins, separated at birth. When they meet again, under the watchful eye of dominatrix Miss Horsfall, it is on opposite sides of the law. Will the girls find out they're sisters? And are the bars and fences to keep the inmates confined, or the locals out?
