My Sister’s Keeper is about Anna Fitzgerald, a 13-year-old girl who enlists the help of an attorney, Campbell Alexander, to sue her parents for the rights to her body. Kate, Anna’s older sister, suffers from acute promyelocytic leukemia, a cancer of the blood and bone marrow. Anna was conceived through in vitro fertilization to be a donor who could save Kate’s life. Her parents initially use Anna’s umbilical cord blood to treat Kate, and continue to use Anna as a donor for other bodily substances as Kate cycles through remission and relapse over the years. Anna eventually petitions for medical emancipation so that she will be able to make her own decision concerning donating a kidney to Kate, who is experiencing renal failure. Sara, her mother, is an ex-lawyer and decides to represent herself and her husband in the lawsuit. She continually attempts to convince Anna to drop the suit, but Anna refuses to do so.
