Ryan O'Hara is a Army Green Beret who is suffering from war wounds and Post Traumatic Stress Disorder. He has been placed on convalescent leave and is traveling across America killing former members of a Marxist domestic terrorist organization responsible for the murder of a San Francisco Police Sergeant, four decades earlier. The police sergeant was O'Hara's grandfather and his death destroyed O'Hara's family. Now Ryan O'Hara is evening the score and bringing the same terror down on the terrorists that they brought down on society. He uses different methods to kill his prey including arson, gunshot and bombing. Along the way he encounters a group of disillusioned former intelligence and military operatives who are after some of the same people albeit for different reasons. He allies himself with them and together they carry out their deadly mission in such a manner that suspicion focuses on the office of the Chief of Staff to the President of the United States. This is a violent tale of vengeance and delayed justice made necessary by a failed system that allows treasonous murderers to escape punishment.
