A happy and successful family man is lured down the destructive path of revenge after his son is killed and his wife brutalized in a vicious home invasion. Thomas Archer (Ron Eldard) had it all, a successful career as a senior associate at a prominent architectural firm, a beautiful wife, and a wonderful child. Just when it seemed that things couldn't get any better for Thomas, however, his life was suddenly transformed into a waking nightmare. One night, a violent criminal breaks into Thomas' home, attacking his wife and senselessly murdering his innocent young son. In the aftermath of the tragedy, Thomas implores the police for help in catching the criminals while attempting to pick up the pieces of his broken life by visiting a highly respected therapist (Christopher Plummer). When local law enforcement fails to turn up any leads, Thomas' therapist suggests that the vengeful father contact a mysterious group with the resources to ferret out his son's killer and let the father exact the any kind of justice that he sees fit. His marriage failing, Thomas decides to take his therapist up on the offer, sending the lives of everyone involved down a dark path from which there is no escape, and no return.
