Lawyers, an ex-police investigator and a former judge denounce Japan's criminal justice system as defendants in a high-profile 2003 election-rigging case in Kagoshima explain how detectives tried to extract false confessions on trumped-up charges of vote-buying. Those who buckled under the pressure and confessed spent over a year in prison. All the "suspects" were finally acquitted, but remain permanently scarred by the ordeal. This documentary is a dramatic reminder that indiscriminate arrests and convictions should be fought with the full force of the law.
