舞台は、巨大な“穴”が現れた日本。入るか悩む8人の男女は、お互いの人生を語り合う――
7 huge holes suddenly appear in locations around Japan. The holes appear in random places like in the sky, in the middle of a road, in a field, or in the middle of the city. Citizens are confused about the holes, and different investigations are carried out about the holes, but the true nature of the holes remains known. As time goes by, people begin to live with these holes. Many people go into the holes, but nobody has returned from the holes.
Then, a man named Ozawa appears who worships the holes as a god. He insists that salvation can be found in the hole. Eight people who are followers of Ozawa gather at a resort facility. The eight people are Kawabata, Sugaya, Matsuoka, Aoyama, Watanabe, Shingo, Iguchi, and Okamoto. Following Ozawa's rule, they must talk about why they want to go and record themselves before they enter the hole.
