Sofia, a young anthropologist, has spent much of her life trying to solve the mystery of her mother's unexplainable illness. She's frustrated with Rose and her constant complaints but utterly relieved to be called to abandon her own disappointing fledgling adult life. She and Rose travel to the searing, arid coast of southern Spain to see a famous consultant, Dr. Gomez—their very last chance—in the hope that he might cure Rose's unpredictable limb paralysis, but Dr. Gomez has strange methods that seem to have little to do with physical medicine, and as the treatment progresses, Rose's illness becomes increasingly baffling. Sofia's role as detective—tracking Rose's symptoms in an attempt to find the secret motivation for her pain—deepens as she discovers her own desires in this transient desert community.
