Watch soap2day. Detectives of the First Investigation Division of the Capital Police Department are investigating the murder of a 15-year-old girl, whose strangled corpse was found in the bay of the Tama River. As usual, the film runs only one hour and doesn’t depart too far from the usual formula; however, it greatly benefits from frequent outdoor locations that were missing from the previous film. It also touches far more serious topics, such as child abuse and mental insanity. 16th work from the popular series "Keishicho Monogatari", which documents the activities of the First Investigation Division of the Capital Police Department.
