Dr. Heather Stapleton is your typical middle-aged professor: a husband, some kids, and bored. Her friend Annie teases her with tales of her latest divorcee adventures, and she's intrigued. Not quite ready for something that risque, but maybe add a little spice to her bland life. When she finally opens her mouth and asks for what she wants, her husband Ron is on board, and soon, things get out of hand. Thank goodness she grades on The Curve.
