A violent criminal called The Butcher is brought back to life by a scientist using electricity. The Butcher becomes an invulnerable mute, and seeks vengeance upon those who caused his execution. Insert the Frankenstein into the Maltese Falcon, dumb it down a bit, and you have “Indestructible Man”.
Keep an eye out for Max Showalter as the Lieutenant on the killer’s trail. He would later play MANY bit roles in Dragnet, a show that seems a direct descendant of this one–“normal” LAPD cops trying to deal with dangerous freaks.
