A robbery and murder occurred at a gas station facing the national highway at 1:00am. Detectives Nagata, head of the First Investigation Division, begins investigating. Two bullets were removed from the corpse of a staff member on duty at the station, and the last car to be refilled with gasoline, Sakura Taxi No. 5-E1044, appears on the line of investigation. The same night, a robbery murder case was discovered using the same US military gun that was used on the gas station victim.

After discovering a slaughtered corpse, the investigating team of the Tokyo Metropolitan Police Department began canvassing the area around the crime scene. As a result, they found a wallet with bloodstains that seemed to belong to the victim, a woman's wallet that did not fit the field, earrings, and other valuable materials, which led them on a foot search. The woman's purse had been picked up by a male prostitute on the subway, and from the prostitute's testimony, they were able to identify the pickpocket's face, but the next day, the man was found dead in a road accident, apparently murdered.
