For seven years, Mia has devotedly loved her aloof husband, Henry, managing the household and raising their daughter. On her own birthday, she travels abroad to visit family, only to discover her husband and daughter celebrating another woman—Evelyn—leaving her feeling like an outsider. Heartbroken and disillusioned, Mia leaves behind divorce papers and resolutely returns home, determined to rebuild her career and regain her independence. Meanwhile, Henry initially dismisses the divorce papers; it is only when Mia completely vanishes from his world that he begins to realize he has lost the most important woman in his life.
