On October 2, at 6:45 AM mass murderer Horace Pinker was put to death. Now, he's really mad.
After being sent to the electric chair, a serial killer uses electricity to come back from the dead and carry out his vengeance on the football player who turned him in to the police.
The film opens with a news report showing a victim being pulled away on a stretcher. It is revealed that a serial killer, having murdered over thirty people, is on the loose in a Los Angeles suburb. A television repairman with a pronounced limp, named Horace Pinker, becomes the prime suspect. When the investigating detective, Lt. Don Parker, gets too close, Pinker murders Parker’s wife, foster daughter, and foster son.
However, his other foster son, a college football star named Jonathan, develops a strange connection to Pinker through his dreams and leads Parker to Pinker’s run-down shop. In a shootout in which several officers are killed, Pinker manages to escape, and targets Jonathan’s girlfriend Allison in retribution.
Another dream leads Lt. Parker and the police to Pinker, whom they catch in the act of a kidnapping. This time, just as Pinker is about to kill Jonathan, he is arrested. Pinker is quickly convicted and sentenced to die in the electric chair.
Prior to his execution, Pinker reveals that Jonathan is, in fact, his son, and that as a boy, Jonathan had shot him in the knee while trying to stop the murder of his mother. But what they do not realize is that Pinker has made a “deal with the Devil”, When executed, he does not actually die but instead becomes pure electricity, and is able to possess others (it is unknown if the possessed hosts live or die after Pinker leaves their body since some of them were shown to be lying motionless after being released) to continue his murderous ways. Some of the people who are killed, are prison staff and Jonathan’s friends…
