After attending three new mom groups, only to be banned for eating Cheetos (not organic!) and uttering the occasional swear word, Sadie Walker questions why she is trying so hard to fit in. While sitting in another dingy community center playroom full of squealing babies and new moms enthusiastically discussing homemade organic baby food, Sadie meets John, a handsome, vivacious dad. They quickly form a friendship and Sadie finally finds an adult outlet. John soon becomes a lifeline and she looks to him for advice and support, and confides in him about her strained marriage and career as a copywriter. Sadie begins to have sexual fantasies about John. Those fantasies turn into opportunity when he tells her he’s in an open marriage. As Sadie contemplates how far is too far in regards to her friendship with John, she must also question herself, her marriage, and her life. Will swinging with John improve that life, or destroy it?
