A violent criminal called The Butcher (Creator/LonChaneyJr) is executed and then brought back to life by a scientist using electricity. The Butcher becomes an invulnerable mute and seeks vengeance upon those who caused his execution.

Film historian Tom Weaver wrote an excellent book about the film as Volume #2 of his ''Scripts from the Crypt'' series (following hot on the heels of Volume #1, ''Film/TheHideousSunDemon''), featuring extensive background information about the film as well the script.
