During the G8 Summit, the monster named Guilala appears in Hokkaido. The U.S. President proclaims, "We will never yield to any terrorist or any monster!" and the Japanese Prime Minister hides behind the back of others. The egoistic world leaders compete against each other to terminate the monster, Guilala. Who will save the crisis of Earth?
In the summer of 2008, the G8 summit is held at Lake Toya, a beautiful resort near the volcano in Hokkaido. At the same time, a Chinese rocket falls into the island, causing the monster to be born from the spore attached to the rocket. The monster, Guilala, moves toward the summit conference site in pursuit of volcanic energy. The US President proclaims "I wil never yield to any monsters! Nobody calls me a chicken." Other leaders reluctantly switch the sign board from "G8 Summit" to "Guilala Task Force". Now they have to terminate Guilala to show their country's power and prestige. First mission is missile attack by Japan, then Italy, Germany and... Deadly combat between human beings and the monster from outer space continues. However, when everyone starts to give up, a journalist finds out a strange group worshipping the traditional idol at the lakeside.
