Mt. Fuji awakens from dormancy after a series of earthquakes, drawing the attention of Gamera. A team of researchers is sent to investigate, but they are lost after a glowing green pit on Mt. Futago emits yellow beams that destroy their craft. A reporter and a boy named Eiichi venture to the site, only to find a giant winged creature, Gyaos, awakened from a long slumber. Gyaos begins hunting warm-blooded prey, and Gamera intervenes to rescue Eiichi, suffering a deep gash in the process. Gamera then retreats to the sea to heal, while the Japanese military and science community search for a way to kill Gyaos.
