During WWII, a human heart taken from a certain lab in Europe (Dr. Frankenstein's) is kept in a Japanese lab, when it gets exposed to the radiation of the bombing of Hiroshima. The heart grows in size, mutates and sprouts appendages, and eventually grows into a complete body and escapes. Later, a feral boy with a certain physical deformity (a large head with a flat top) is captured by scientists who refer to the boy as Frankenstein. The creature grows to the height of 20 feet, escapes again, fights police and army, and is practically indestructible. Later, a reptilian monster goes on a rampage. Eventually the Frankenstein creature and the reptile face off in a terrible battle.
