Concussion

Abby, an attractive 40-something, wealthy housewife who, after getting smacked in the head by her son's baseball, walks around every corner of her suburban life to confront a mounting desire for something else, something more. Determined to take on a new project, she buys a pied-à-terre in Manhattan. But walking around the city streets reminds Abby of what it feels like to be sexy and her pent-up libido compels Abby to invent a secret double life that draws her deeply into the world of high-end prostitution for women.
