Man in custody at a mental hospital claims to have witnessed a rape in a break room. Despite the witness' shaky credibility the SVU begins an investigation, but the alleged victim, Gia Eskas, denies being assaulted. Detectives Benson and Rollins struggle to piece together what really happened to this young woman, especially when her aunt and mother say Gia has been repeatedly institutionalized, and has cried rape in the past.
