He has every intention of delivering on that promise but then he gets the worst news of his life. He's dying. Now he's on a quest to fulfill his bucket list and make sure Emily doesn't pine for him when he's gone, because even billionaires can't buy the cure for his cancer. But Emily is determined to see him through his illness and business rivals are determined to make sure his dreams don't come true. David must face his own mortality and Emily must come to terms with the fact that the love of her life may be ripped from her at any moment. The odds of their love surviving seems hopeless, but they are surrounded by a group of friends who think it's worth the fight.
