By day, Sandy Davis is a dedicated social worker. By night, she's found an unlikely pastime: spying on her neighbours' erotic encounters. She tells herself that it's harmless, until one night she finds herself on the receiving end of such a fantasy - and an anonymous phone call from a peeping tom who calls himself Justice, and whispers You've been a bad girl. The arousing predicament turns into a sensual dance between the adventurous pair. But when a third player enters their sexy game, the fun turns to something darker and more dangerous.
