Vowing to never marry before his forty-fifth birthday, Anthony Cross, a successful, up-and-coming plastic surgeon, likes to keep his relationships casual. Looking for a one-night stand, he stumbles upon a mature woman with a ring already on it. Gracie Lane, the married, mysterious temptress, eventually triggers all his stressors with her incessant lies, secret past, and constant mood swings. She's too much for one man to possess, but that doesn't stop Doctor Cross from trying.

As Gracie pulls away, Anthony's grip tightens, and the self-proclaimed bachelor realizes that Gracie's in control and he's become her HISTRESS!
