Ellen and Andy's marriage doesn't just seem perfect, it is perfect. There is no question how deep their devotion is, and how naturally they bring out the best in each other. But one fateful afternoon, Ellen runs into Leo for the first time in eight years. Leo, the one who brought out the worst in her. Leo, the one who left her heartbroken with no explanation. Leo, the one she could never quite forget. When his reappearance ignites long-dormant emotions, Ellen begins to question whether the life she's living is the one she's meant to live.
