Lily (Susan Sarandon) is a woman who is very loyal to her heart. So when she learned that she had an incurable disease and was dying, she made a crazy decision-to commit suicide while she was still able to control her own destiny. In order to announce this decision, Lily called her two daughters Anna (Mia Wasikowska) and Jennifer (Kate Winslet) back to her side, along with Lily's childhood friend Liz (Lindsay Duncan). Of course, the family could not support Lily's suicide plan, and Anna and Jennifer began to try every means to hinder it. At the same time, Jennifer was shocked to find that her father, who seemed to be a good man, actually had an unknown underground love affair with Liz.
