STORY

Are all sins inherently evil? Three men who have lived their lives unable to escape their childhood sins are forced to reexamine themselves after a new murder takes place in their insular hometown.
A backwater country town in Fukui Prefecture is home to best friends Haru, Akira, Masaki, Saku, and their younger brother Naoya. Their lives are suddenly upturned one day when Masaki's dead body is found in the river that runs through the center of town. As the small town becomes awash in fear, Haru, Akira, and Saku visit a creepy old man who lives on the outskirts of town whom they suspect murdered Masaki. But in their heated confusion to get at the truth, they end up killing him. Haru insists that he alone should take the blame, and burns down the old man's house. Twenty years later, a boy's body is found in the same river where Masaki died. Akira, who has returned to his hometown as a detective, is assigned to the investigation. The trail of the murdered boy leads him to a surprising reunion with Haru, who has led a local crime syndicate since his release from a juvenile reformatory. The latest murder opens up old wounds of sin and guilt as the two begin to question who was really responsible for Masaki’s death years ago, leading them to a reunion with Saku. Confronted once again with the crime they committed years ago, the former best friends eventually arrive at a horrifying truth.
