At the insistence of DAC Strickland, the team reopens an unsolved case wherein a circus owner, Bert Digman, was found burned to death in his caravan. The man's daughter is now a successful businesswoman and she is pushing to have the crime solved. Forensic tests, however, confirm that the remains found in the caravan are not related to the woman. Her mother gave her up for adoption and will have no contact with her. Meanwhile, Sandra's mother suffers a mild stroke. Sandra also learns that Jack had investigated her father for corruption and, for the first time, exactly how he died.
