Subtitle: Did a Police Detective Kill a Cop? After Being Seduced by a Woman in a Red Dress... What Is the Mystery Behind the 4-3 Left on the Corpse?(刑事が警官を殺した? 赤いドレスの女に誘惑され... 死体に残る4-3の謎とは?)
The very first episode of the series. We get to see most of the main cast make their first appearance, including Inspector Ukyō, Sergeant Kaoru, and his lover Miwako who is a journalist for the Teito Newspaper.
Sergeant Kaoru attempts to arrest a wanted criminal Kisaburō Abe(阿部 貴三郎) but is taken hostage instead. This incident is broadcast live on TV, embarrassing the Tokyo Metropolitan Police Department. As a result, Sergeant Kaoru is transferred to the Tokumeigakari division, the "graveyard of human resources." Berated by Inspector Ukyō and upset at his condition, Sergeant Kaoru drinks until he passes out at a bar named Bar Refrain. Things go from bad to worse as he wakes up inside an unfamiliar apartment with a dead man who turns out to be a cop in the next room.
Can the Tokumeigakari pair clear Sergeant Kaoru's name and find the real killer? How is this case related to the sales of illegal firearms?
This is also the one and the only episode where Inspector Kaneko(金子), Inspector Ukyō's senpai, makes his appearance.
