Her name is Anna, who since the age of 5, has had blood taken from her and been put thru medical procedures to help keep Kate alive. Anna loves Kate, played as a teenager by Sofia Vassileva, but when her parents want to give Kate one of Anna's kidneys, Anna finally says enough. Sure that no one is looking out for her interests, Anna hires a lawyer (Alec Baldwin) and sues for the right to her own body.
