It has been 2 months since the events of "SP: The Motion Picture". The members of the Security Police Department’s Section 4: Inoue Kaoru (Okada Junichi), Sasamoto Eri (Maki Yoko), Yamamoto Takafumi (Matsuo Satoru) and Ishida Mitsuo (Kamio Yu) are taking a brief day off from their daily duties. However, around that same time, Ogata Soichiro (Tsutsumi Shinichi) and the others are proceeding with preparations for the “plan” to come. Tanaka Ichiro (Nomaguchi Toru) of the Public Security Department has continued with Ogata’s identity check and finally reaches a shocking truth... Inoue and the rest do not yet know... that an unprecedented situation is about to rock Japan 24 hours later.
