After rigorously preparing for a qualifying exam, journalist Jake Adelstein is hired as the first American crime reporter for Japan's prestigious newspaper, Meicho Shimbun, where he's quickly tasked with covering the case of a stab victim.

After receiving a terrifying video tape, Jake enlists Detective Katagiri in pursuit of the truth behind Polina's disappearance... but must tread lightly due to the involvement of a government minister. As Samantha takes steps to launch her own club, the Chihara-kai closely monitor a gravely-injured Sato - but not all members are eager for his full recovery.

With Katagiri sidelined at work and Jake intentionally off the yakuza beat, both search for new meaning in their work. As Jake pursues an uptick in motorcycle theft, Samantha confronts a thief in her club, and the Chihara-kai welcome back former member Hayama, who has returned as Sato's superior.

After Katagiri partners with Nagata, the detectives ramp up their task force's efforts to take down the city's yakuza organizations. As his coverage of motorcycle thefts gains momentum, Jake receives an invite to an exclusive party - and boldly brings along a special guest. Meanwhile, Samantha and Sato deal with a growing problem at the club.

Katagiri and Nagata's task force gains momentum, while an oyabun's mysterious return at a yakuza summit triggers a new investigation by Jake. As Katagiri and Jake dig into the mysterious return, Samantha must decide if she'll do a favor for Ishida, and Sato and Hayama are forced to travel north on an expedition.

Samantha tries to make amends with Masa while delivering on her promise to Ishida. Later, Jake and Katagiri attempt to pursue their elusive target without landing in his crosshairs. On their way back from the north, Sato and Hayama strategize a way forward.
