After the death of their mother, three sisters return to the small English coastal town where they had lived as girls, each weighed down with their own troubles. Teresa (Julie Walters), the eldest, is unsure about the future of the business she runs with her husband; middle-sister Mary (Joanne Whalley) is concerned she might be pregnant; and Catherine (Victoria Hamilton), the youngest, has troubles with her Spanish boyfriend. Arguing about events in the past, the three women remember what their mother meant to them and edge towards significant changes in their own lives. Based on the play "The Memory of Water.".
