Three skeletons are found in the basement of a pizza parlour. The building is old, with a colourful past, and Homicide Detective Luc Claudel dismisses the remains as historic. Not his case, not his concern... But Forensic Anthropologist Tempe Brennan has her doubts. Something about the bones of these three young women suggests a different message: murder. A cold case, but Claudel's case nonetheless. Brennan is in Montreal to testify as an expert witness at a trial.
