For 10 comfortable years, Sally (Catherine Shepherd) has lived with David (Alex Macqueen). Life is good, even if David is boring and she can't always tell when they're having sex. And then Emma (Julia Davis) happens, seductive, charismatic and bohemian, Emma is everything David isn't, and an awful lot more besides: she's an actress, a singer/songwriter. A musician. An author. Also a poet.  So it's no surprise that Sally embarks on a wild affair with her. Before she knows it, Emma has moved in, rearranging the furniture and her life.  But is this really what Sally wanted?!
