A schoolgirl who has been missing for weeks returns home covered in bruises. She says two women kidnapped her, held her captive in an isolated house and beat her. Taken by the police to the house she described, she identifies it and the mother and daughter who live there. They call in a lawyer, who has only days to find evidence that will break the girl's story.
