Frankenstein vs. Baragon

In 1960, a feral boy runs rampant in the streets of Hiroshima, devouring small animals such as dogs and rabbits. This comes to the attention of American scientist Dr. James Bowen and his assistants Sueko Togami and Ken'ichiro Kawaji. Kawaji, who brought the heart of the Frankenstein Monster to Japan in WWII, is now working in an oil factory in Akita Prefecture, when a sudden earthquake shakes the very foundations of the refinery and an offshore drilling tower collapses. Meanwhile, Dr. Bowen and the scientists find that the strange boy is growing in size due to intake of protein.
