Cold cases

FBI agent Gardner Camden is an analytical genius with a passion for puzzles. However, the human element of investigation is his weakness, which sometimes has a negative impact on those closest to him, especially his seven-year-old daughter Camila. Gardner and his brilliant but eccentric colleagues from the Predictive Analysis and Review (PAR) unit work on cases that no one else at the FBI can crack.

When DNA tests identify the victim of a violent crime as a serial killer, there is just one problem – the man has been dead for years. The PAR team must spring into action. Another murder soon follows, and the perpetrator leaves behind a trail of clues and riddles aimed directly at Gardner. Although his team has previously solved cold cases strictly from the office, they must now head out into the field to hunt down the killer.

Led by experienced agent Frank Roberts, the PAR unit includes Gardner, a mathematician, a weapons expert and a computer analyst. Together, they must use all their skills and knowledge to track down the killer. But the killer also knows a great deal about each of them… Can they protect themselves and their loved ones?
