After a robbery, three of the gang set up the other member to take the blame and he is sentenced to death in the electric chair. His body is sold to a scientist who brings him back to life as indestructable. He then goes off to kill the other three in the gang but a policeman is tracking him down with the help of a dnacer who was his ex-girlfriend. The underlying premise if of a sci-fi film, but this is more a revenge film with the crime drama coming from the police tracking the man down. There are problems and holes in the plot which is not a surprise with the sci-fi premise. Lon CHaney Jr is solid if unimaginative as the lead character.
