霧の旗 (1977)

Masao is falsely accused and jailed for the murder of a loanshark to whom he owed a lot of money. His sister Kiriko makes the long trip to Tokyo, specifically to accost Otsuka, Japan's top criminal defence lawyer, and plead with him to take her brother's case. They live in Kitakyushu which, though a city, she contends that the local lawyers are not up to the job. Otsuka contemptuously brushes her off. A year passes. Masao has suicided in jail, his appeal having failed due to the lack of interest and competence of the local defence lawyer. Kiriko returns to Tokyo, planning revenge on Otsuka for refusing the case and causing her brother's death.
