Can brothers and sisters get a divorce from each other? Yes, and sadly enough, some do. After her parents' death, Molly (Elisabeth Shue), a mentally challenged girl, was institutionalized. Her brother Buck (Aaron Eckhart), always uncomfortable with her, has only visited once a year. Now the nursing home where she resides is closing down, and she must come to live with him.

John Duigan directs this drama written by Dick Christie. When Buck learns that Molly qualifies for an experimental operation on her brain by Dr. Susan Brookes (Jill Hennessy), he gives his permission. His sister receives the moral support she needs from Sam (Thomas Jane), a developmentally disabled employee at the hospital. Molly is transformed from a fearful, shy, and semi-autistic person into a confident, radiant, and smart woman.

Although the accent of the story is on the medical procedure, the real emotional undertow comes in the exploration of this uneasy brother and sister relationship. Molly's love for Buck is unadulterated, but he is unable to accept her as she is until he begins to see her important place in his life. In a world desperate for any kind of kinship, the ties between brothers and sisters remain an invaluable and often unexplored treasure.
