The phone is ringing as Julia opens the front door. Despite being a capable professional woman, she holds her breath, tries to still her pounding heart, and makes herself quiet and small as she lifts the receiver. It's been more than a year since she broke away from the influence of an anonymous caller with whom she had developed an intimate relationship. He knows all her innermost secrets. One day soon, when she answers the phone, it will be him. He'll be back, as cool, calm, and collected as ever, but Julia is a stronger woman now, determined to expose him. The shoe is on the other foot, as the caller - whom she has known as Stephen - is now under her thrall. There are many false starts and uncomfortable moments on a journey she may wish she had never started.
