Composer Steven Lauddem (Peter Dinklage) is suffering from creative block and unable to finish the score for his big comeback opera. At the behest of his wife Patricia (Anne Hathaway), formerly his therapist, he sets out in search of inspiration. After a chance encounter with Katrina (Marisa Tomei), everything Steven thought he knew about his life is upended, and what he discovers is much more than he bargained for, or imagined.
