After twenty years of marriage, Ben ups and leaves his wife Rose, their children and their family home in Dublin. Just like that: no words of regret, no compromise, no note - only a simple "I don't love you anymore".
It has taken Rose all this time to get her life together again: she's brought up her three children, Lisa, Brian and Damien single-handedly. Now Rose is concentrating on her business, the "Bonne Bouche" bakery, and all the clients she's won, all the friends she's made. Her accounts are in order, the business is blooming. Life really doesn't seem too bad. Until Ben returns, again without warning, and it is soon clear that he expects to infiltrate Rose's carefully created world in the most unwelcome of ways.
