Three daughters take care of their mother, who has suffered years of pain and hospital treatment for cancer that is present in both her lungs and brain. The sisters have never gotten along very well, living now miles away from each other in Florida, but in their late 20s to mid-30s now, the eldest moves in with the middle child, Jo, and the two can stand each other for the most part. The youngest daughter, Arlene, has had problems on account of her mental health, and she's been ostracized from her sisters because of her desperate need for love from their abusive step-father, Jack. She refers to him as Daddy, though all three have at one point wished him dead, whether it be at their hands or due to fate. In trying to provide comfort to their mother, the girls bring her to live at her home, where they care for her until her last day. On a shopping trip with her eldest daughter, the mother gets into an altercation with a woman who had been preaching about God's good grace. She gets right up in the woman's face telling her about what she's learned of His grace, how it comes in the form of laborless breathing or the absence of pain. Caring for their mother at home, they need to get Jack to sign papers regarding what to do in case of resuscitation. The women are trying to do what is thoughtful for their mother, whom they see in agony daily. It is Arlene who gets Jack to sign the papers, which he likely would've declined had the other women asked. One night, the daughters hold their mother's hand as Arlene hums to her, and she dies in their arms.
