Kate is getting married in a month. Richard, her fiancé, is a lawyer: rich, successful, and very good-looking. She's definitely in love with him. No doubt about that.

So when Sam, a good friend and her high school crush, returns after eight years of traveling, she doesn't care. After all, he never actually asked her out, and then he went traveling without her, contrary to their plans. She only agrees to go to dinner with him in order to hear all his news, so why doesn't she tell him she's getting married? And is he still bothered by the tragedy eight years ago?

Sometimes life just gets too complicated, and Kate finds she keeps having Very Bad Ideas, which lead to even more complications. Just three days before her wedding, she finds herself in a situation that demands the biggest decision of her life.
