Two years ago, Katsuo Todo (Takashi Naito) was appointed as the general manager of the Plato Royal Hotel Yatsugatake from the Plato Tokyo hotel. He works hard every day with his staff to provide the best time and space for our customers. Concierge Shuji Kitayama (Hishine Saku Toshihide) struggles to find a benefactor for guests Pascal Henry (Frederick Benoliel) and his wife Shizuko (Ishino Yoko). The sweets made by young pastry chef Yoshiyuki Sudo (Shunsuke Tanaka) are popular with guests, and popular writer Fuyuki Nakagami (David Ito) even stays just to enjoy them. Sudo has also decided to marry Minori Matsuoka (Rio Yamashita), and Minami Yamashita (Michiko Amekumi), who is in charge of bridal services, is busy preparing for her colleague's wedding.

Kohiruimaki Yuichi is a police officer who established the "Science Crime Countermeasures Office", a department that specializes in issues related to cutting-edge science and technology. He welcomes the genius scientist Mogami Yukiko as an advisor and she is in charge of investigating cases related to cutting-edge science. The crimes entrusted to the Science Crime Countermeasures Office are crimes that the legal system and police organization cannot keep up with. The two will unravel the science itself hidden behind the cases and not just the so-called forensic investigation. Hasebe Tsutomu is a detective who is not familiar with science but has a long experience in the field in the former Investigation Division.
