Anna is usually willing to donate whatever Kate needs, but when she turns 13, she is told that she will have to donate one of her kidneys due to Kate's kidney failure. The surgery required for both Kate and Anna would be major; it is not guaranteed to work,as the stress of the operation may kill Kate anyway, and the loss of a kidney could have a serious impact on Anna's life, since Anna is fond of hockey. Anna petitions for medical emancipation with the help of lawyer Campbell Alexander, so she will be able to make her own decisions regarding her medical treatment and the donation of her kidney.
