Kasia Lyndon is a good-looking but struggling young actress who is thrilled to get her first break at the Craven Playhouse, a privately owned theatre company in a country manor house. But this is no ordinary theatre, and she must live her role both on and off stage - even when it demands that she submits herself to her sadistic leading man and his mistress. Kasia, however, soon discovers that this domination has unleashed feelings in her that she never dreamt she had.
