Scriptwriter Yuki and assistant director Anan visit the Shirato family, an old family home in Yamanashi, for a location scouting trip for a horror show. The house is said to be cursed, with a legend that "boys die there at the age of 12." Furthermore, Yuki learns that the producer's son from a previous marriage, Kota, will soon turn 12. Yuki dismisses it as a coincidence, but Anan begins his own investigation. When he examines the ancestral tablets left in the house, he uncovers the terrifying truth behind the curse.
