In order to find out a series of abnormal crustal movements in the Japanese islands, geophysicist Dr. Xiosuke Tansuo (Kobayashi Kobayashi) and his assistant Nobuhiko Koichang (Yuke Hisuke Hakata) went out to sea on a submarine driven by Toshio Ono (Hiroshi Fujioka). In the trench near the Ogasawara Islands, the doctor was worried about the inexplicable mudflow at the bottom of the sea. After a careful and careful investigation of the materials of all parties, Dr. Tian Suo made a prediction that shocked the whole country and even the world, "due to the changes of the earth, Japan will completely sink to the bottom of the sea within two years." His prediction was not fully trusted by the government at first, but after that, strong earthquakes erupted and extinction volcanoes erupted again, and things are deteriorating at an unexpected rate. In this isolated island, the people are in an unprecedented madness. This film is based on the original work of Komatsu Zuojing of the same name.
