A new documentary movie portrays the new daily ordeal of a man who lived for almost half a century in solitary confinement and in fear of the gallows.

"Freedom Moon" depicts the daily life of Iwao Hakamada, a former boxer who served 48 years in prison for murder, most of it on death row. It also features his sister, Hideko, who campaigned tirelessly for his exoneration.

Tragically, the film shows how Hakamada's decades of solitary confinement and fear of execution have resulted in a badly deteriorated mental state. He paces his apartment and sometimes is unable to express his thoughts clearly.
