Former boxer Charles Nyack is paroled after serving two years in prison for assault. He is planning revenge against the woman whose testimony but him behind bars. When his friend who is driving him from prison objects to his plans, Nyack knocks him out and leaves him by the wayside where he later dies. A massive power blackout complicates the FBI's efforts to find Nyack before he kills his intended victim, who is staying with her mother in a remote house. (thetvdb.com)
