Is there a future in playing stand-in to a slave? Sarah Gladstone was thrilled to be offered her first real acting job at the Berks Summer Playhouse. She never expected to be working with theatre legend Geoffrey Hart. The charismatic actor quickly brings her under his spell, not to mention his control, as he initiates her into the dark delights of BDSM. He offers her far more than physical pleasure; they share a level of intimacy and trust beyond anything Sarah could have imagined. According to the rumours, though, Geoff's heart is taken. Renowned actress Anne Merrill, his long time partner and submissive lover, has severed their relationship and Hart has escaped to the Berkshires to lick his emotional wounds. With her youth, inexperience, and girl-next-door persona, Sarah knows that she can't compete with the glamorous theatre veteran. She fears that she's just a substitute for the real object of Geoff's affections. As he draws her deeper into his intoxicating games of dominance and submission, Sarah wonders if she's willing to settle for the role of understudy in this perverse passion play.
