Three years ago, then-Kōnan Takaaki (Oku Tomoya), a student at K University, chanced upon Shikatani Monzane (Aoki Munetaka), real name Shimada Kiyoshi, before he made his debut as a writer. Three years later, after graduating from graduate school and joining a publishing company, Shikatani reunites with him for the first time in a long time. A novice editor, he visits a certain mansion with the deputy editor-in-chief, a cameraman, and students from W** University to cover a special feature for the occult magazine he oversees, titled "Challenging the Ghosts of the Clock House in Kamakura." The mansion is a strange mansion also known as the "Clock Tower," apparently one of the buildings designed by the famous "Nakamura Seiji." For three full days, Konan and his team hole up in the former Clock Tower building with the students to hold a full-scale "séance" featuring the up-and-coming female psychic, Komyoji Mikoto, as a medium.

"I want you to investigate the meaning of the poem 'Goddess of Silence' left behind by the owner of the Clock Tower," is the request that Shikatani and Fukunishi make to visit the Clock Tower again. The two are shown around the interior of the clock tower and several rooms in the new building, and are led to the study that was meant to be used by the previous owner. They hear about the unfortunate events that occurred in the house in the past. Meanwhile, in the old building, one of the participants is killed by an unknown assailant. Entrance is blocked by a sturdy door, and Jiangnan and the others are still trapped inside the old building, which has become a closed room. Then, the masked figure approaches them again.
