The story describes how two cases of people poisoned to death by hydrogen sulfide at hot springs in two separate locations seem unrelated at first but it turns out that they were acquaintances. As such, the police approaches Professor Aoe Shusuke (Sakurai) who is also a geochemist to assist in their investigations to confirm if the deaths were due to accidents or foul play. During the process, Aoe meets a mysterious girl Uhara Madoka (Hirose Suzu) who appears at the crime scene and seems to have the power to predict when a natural phenomenon will happen. While Aoe is trying to ascertain if Madoka is involved in the cases, Madoka will be searching for a missing young man Amakasu Kento played by Fukushi Souta.
Filming began from 16 March and is expected to wrap up in late April. The movie will be shown in 2018.
