Diet member Daisuke Iwata (Minoro Sado) is found dead in a hotel room with a pistol in his hand. Presumed suicide, Furuhata has doubts about the initial conclusion due to the clues found in the room. After discovering the victim dialed a wrong number several times, Furuhata believes Iwata was trying to contact media planner Kazuo Yura (Hiroyuki Sanada), who claims he was on the phone with his secretary during the time of death.
