The story starts off on a southern island in the near future. Yoshii has a dark past himself. He was once a detective, but he stabbed his wife when he found out she was having an affair. Now he works on the island as a landmine remover. One day, his coworker, Junichi, steps on a landmine and dies. A few days later. Yoshii and his boss, Takahashi, go to Junichi’s apartment to give their condolences. When they get to the apartment, Yoshii is surprised when Junichi’s wife greets them-it’s Mikayo. After the incident with Junichi, Yoshii decides to quit his job as a landmine remover and begins to spend his days next to a cave, fishing. One day Yoshi takes out an old paper from his belongings; the paper fugitive warrant, and on the warrant is a photo of Mikayo.
