Orphaned, then abandoned by long-term foster carers, teenager Sophie lives with Amy and Matt. For a long time and unknown to others, Sophie has been self-mutilating: more recently she has been in therapy. Concerned about Sophie's increasing depression, the doctor admits her to a hospital. There Sophie is placed in an adolescent ward where she forms tentative relationships with other troubled teenagers and begins sessions with psychiatrist, Helen Marshall. However, the doctor crosses the patient-therapist line, but so too does Sophie.
