A omnibus movie consisting of the three parts: "Kechinbo", "Yowak" and "Kōshoku".
Freelance reporter “Scoop” Machida is hot on the trail of a prostitution ring called the Black Line, when he is framed for the murder of a young woman. Forced to clear his own name, the handsome journalist sinks deeper into the Black Line’s rotten swamp of drugs, prostitution, and murder and finds unexpected help in Maya, a steamy female gambler familiar with the neon-lit streets, shadowy alleyways, and seedy nightclubs he must navigate. The closest film in the Line series to classic American film noir, Ishii’s Black Line is a pulpy assortment of crime film conventions including the starkly expressionistic black and white cinematography by Jûgyô Yoshida, a jazzy music score by Michiaki Watanabe, and a sleazy screenplay by Ishii and Ichirô Miyagawa.
For the poor, Edo is Hell on Earth, starving under the rule of Tanuma Okitsugi, corrupt councilor to the shogun.

Tanuma’s henchmen will hire an evil swordsman to pose as Kageboshi, starting a wave of murder, kidnapping and robbery, searching for two antique sword-guards that will reveal the hiding place of a fortune in buried gold. But who will claim the gold? The poor of Edo, or the conniving Tanuma? Only Kageboshi’s flashing sword, tearing through Tanuma’s bloodthirsty minions, can forestall his wicked schemes.
