Although not autobiographical, the story was partially inspired by Passon herself suffering a mild concussion, in the same manner depicted in the film, shortly before she began writing the screenplay.

One afternoon, Abby's son Jake accidentally hits her on the head with a baseball and she is rushed to the emergency room by her wife, Kate, a divorce attorney.

After an unsatisfying sexual encounter with a prostitute, Abby makes arrangements through her employee, Justin, to sleep with a young woman named Gretchen.

Abby realizes that she also enjoys having access to new sexual encounters as they provide an escape from her monotonous life; she decides to take clients on a weekly basis.

She meets with The Girl, Justin's business partner and new girlfriend, who agrees to send interested women to Abby in exchange for a small fee.

Abby creates her alias, Eleanor, and meets with every potential client at a coffee shop as a precaution, only inviting them to her private loft to have sex if she deems them safe.

Soon enough, Abby has sexual encounters with a wide variety of women, eventually becoming entangled with Sam Bennet, whom she recognizes from spin class.
