Kiriko was in deep despair. Amidst her barely manageable life relying on her meager pension and part-time income, her best friend and sole source of consolation had just died, and she was suddenly facing days of emptiness. Then one day, she sees on TV a man arrested for theft, claiming that he had nothing left to hope for in his life and that he had committed his crime for the purpose of going to prison. Inspired by this thought, she sets prison as her final home and begins to search for ways to get arrested with the least amount of trouble caused to other people. (Source: nhk.or.jp)
