Plot: Clyde Shelton is an upstanding family man whose wife and daughter are brutally murdered during a home invasion. When the killers are caught, Nick Rice, a hotshot young Philadelphia prosecutor, is assigned to the case. Over his objections, Nick is forced by his boss to offer one of the suspects a light sentence in exchange for testifying against his accomplice. Fast forward ten years. The man who got away with murder is found dead and Clyde Shelton coolly admits his guilt. Then he issues a warning to Nick: Either fix the flawed justice system that failed his family, or key players in the trial will die.
Soon Shelton follows through on his threats, orchestrating from his jail cell a string of spectacularly diabolical assassinations that can be neither predicted nor prevented. Only Nick can stop the killing, and to do so he must outwit this brilliant sociopath in a harrowing contest of wills in which even the smallest misstep means death.
