Sergeant Croft has long despised the spoiled upper class princesses who are always used to getting their way in civilian life. Whenever one of them winds up in her unit, under her authority, she always stakes special pleasure in making their military training as miserable as possible. This is why she volunteered for special duty at the stockade. The spoiled, stubborn enlisters eventually wind up here for special discipline training. Sergeant Croft has her own training methods. She has her ropes, straps, and whips. She also has a particularly painful device known as the bondage horse. She revels in subjecting prisoners to the careless moment when she let her guard down. Her prisoners overpowered her and took her captive. Now Sergeant Croft is really in a bind!
