Joanne Fleming likes to be watched; it ignites a desire within her that's hard to control. Her neighbor, Steve, has a secret of his own: he likes to watch. Their passion burns hot as they fulfill their fantasies - until Joanna meets and falls in love with Eric Seaver. Now she's forced to make a choice, not just a choice between two men, but what might be a choice between life and death.
