Shinichi is a good guy serving three years and approaching the end of his time. He escapes handcuffed to dangerous Gunda, who instigated the escape. Thus tethered, they start out on a journey across the desolate snow country of Hokkaido.
Shin'Ichi returns home to visit his mother's grave. Upon returning he finds the mess that his previous reckless behavior left behind. His old boss, Asahi, was attacked after Shin'Ichi left and was forced to give up a lot of of his power.
