Danny is struggling to establish himself as a writer in Toronto when he receives a call from his former roommate, best friend, and the love of his young life, Isabelle. Over a casual coffee, she speaks the three words – I love you – he has been waiting five years to hear, though she is no longer the picture of confidence and calm he remembers. What follows is an emotional and physical journey, with stops in New York and Scotland, that will push Danny and Isabelle to the limits of sanity and have them question their deepest meanings of love, sex, friendship, and relationships.
