Due to a volcanic eruption, the remote island of In’oku-jima was left uninhabited, untouched by human footsteps for years. Now, a group arrives with plans to turn the forgotten island into a business opportunity: a team from a folklore research lab, a resort development company, and a band of eager video streamers. But what awaits them is no paradise— it is a nightmare beyond hell itself. On an island where escape is impossible and no help will ever come, only one fate lies ahead: death. Can anyone survive the monstrosities that lurk in the shadows of this cursed land?
