One night, while entertaining clients at a club, Kiyota loses his temper and punches a customer. The club happens to be protected by his high school classmate Kenji Hosokawa (Sho Ikushima). Kenji knocks out the rampaging Kiyota with an ashtray. When Kiyota wakes up, he finds himself in Kenji’s office. Kenji invites him into his yakuza group, telling him this might be his one chance to turn his life around…

Kiyota Akira (Ryusuke Nakamura) and his former classmate Kenji Hosokawa (Sho Ikushima) begin making money using boat-race betting tricks. Kiyota eventually becomes favored by Yamazaki (Taketarino Yamaguchi) and surpasses Kenji’s results, causing resentment to build within Kenji. Ignoring Kiyota’s warnings, Kenji breaks the strict rules of their boat-race scheme in an attempt to earn big on his own—marking the beginning of his downfall. As his funds dry up, Kenji plans to rob the office of Fujiyoshi (Shinra Manzo), the group’s treasurer. He thinks he can get away with it—but…

Akira Kuroda (Keisuke Kida) becomes a hitman for the Sannotokai Ogata-gumi and attempts to assassinate Kumao Masatsugu (Hideo Sato), the young boss of the Kugizaki-gumi—but fails and is seriously wounded. Now both Fujita (Tsukito) of the Washizu-gumi and Kumao are out to kill him.

Determined to prove himself, Kuroda begs Kiyota to let him officially join the organization. Fellow hangure Shirai (Takuya Shinagawa) also applies, and both are accepted as live-in apprentices of the Washizu-gumi. However, what awaits them is a world far more brutal than they ever imagined…
