This is the story of Dynamo Dan, a sideshow worker who does a faked electrical act. Perhaps because of this he's the only survivor when a bus he's on slams into a high tension tower and all the passengers are killed by the electricity. Dan ends up working with Lionel Atwill a mad scientist trying to make electrified super humans.
Yes, its as corny as it sounds but then so are the Frankenstein films. Corny or no the film is a great way to spend an hour of your time on a rainy night.When most people think of the Universal horror films in the 1930's and 40's they tend to think of the Frankenstein/Dracula/Wolfman movies forgetting or unaware that Universal turned out a a number of very good second tier horror films at the same time. This is one of them.
Warning: do not confuse this with The Indestructible Man which has a similar plot line but which is not particularly well made.
8 out of 10 on a rainy night with the lights off and your best honey by your side.
