Writer Nao (Miko Nakagawa) comes to a certain isolated island. The other-worldly motel guest is stage actor Ginji ( Mitsunari Sakamoto), who is staying to prepare for a role. The owner, the master (Hideaki Hachiya) welcomed Nao.

There, Naruse (Kazunari Moriwaki) and Shimamura (Hiroyuki Hagita), who have escaped from a prison on a neighboring island. In addition, two women, Chinatsu (Sayoko Hagiwara) and Ryoka (Michiko Makino), who have nowhere to go because the road from the city was blocked by a landslide due to a sudden storm, arrive. Wakeari humans appear one after another. Shortly after, the news of the jewel robbery murder that happened in the city was heard on the radio. The perpetrators are said to be two women.

Meanwhile, detective Kuroneko (Kyoji Kamui) receives a request from Nao's older sister, Kaori (Takahashi Aiko), to help her sister. Nao was arrested as a suspect in a murder case, but at the trial, due to certain circumstances, she was found not guilty. Inspector Aso (Shinsaku Kudo), who was asked for cooperation by Kuroneko, and Misato (Chiei Hiratsuka), a psychological counselor, proceeded to interview all seven people who were there about what happened on the solitary island.

"What are the detectives trying to do?" What does it mean to "save" Nao, who has already been found not guilty? Everything was related to Nao's "certain special symptoms".
