One True Thing (1998)

Few moments in life are as powerful, emotionally charged or rife with humor as returning home to visit your parents as an adult. For ambitious New York journalist Ellen Gulden, the journey back to her quaint hometown in the midst of a crisis is all of those things. Returning home to help her father care for her terminally-ill mother, Ellen must confront a relationship with her mother that has always been strained. While Kate is a homemaker with small town hobbies, Ellen worships her father as an intellectual who nurtured her own writing aspirations. But when her father's behaviour is revealed as less than perfect, the balance of her family is altered. In the face of her mother's impending death, Ellen is forced to reevaluate everything she thought she knew about her family, her past and even her life itself.
