From 9.00 p.m., Sundays, 16 January – 20 March 2022
Japan is surrounded by the sea on all sides and has many rivers, lakes and water sites. Despite numerous cases where dead bodies are dumped or hidden in water, the rate at which these are solved is lower than cases that happen on land. This is because it is fraught with many dangers and difficulties. Niina Masayoshi is the leader of the Deep Crime Unit, known as DCU. This new team of specialists formed by the Japan Coast Guard in 2022 investigates underwater incidents and accidents. Their mission is to solve cases that happen in the seas, rivers and lakes across the country which are difficult for police investigations, and to defend that coastline against terrorism. Niina may disregard the rules but he never gives up on his pursuit of the truth. He will not tolerate the sea being soiled and the truth remaining unsolved. Together with the members of the DCU including Nishino Toma, an elite coast guard officer; and Seno Haruki whose life Niina once saved, Niina dives underwater to solve all sorts of difficult cases and confronts the evil lurking beneath the surface. They are given the authority to investigate not only at sea and in the water but also on land, and this creates friction with the police. Their first investigation takes place at a lake formed by a dam in Gunma Prefecture. A major typhoon that made land a few days ago changed the current in the lake, leading to the discovery of the fragments of a person’s skull. When the DCU dive in to investigate the bottom of the lake which has a depth of 100 metres, an unexpected scene spreads out before them.
