Japanese anarchist Toshihiko Kamata is serving a life sentence for a series of bomb attacks in 1971. His letters from prison link his militant past and present life in prison with critical observations of the sociopolitical situation in Japan and the world. In the film fragments of his philosophical and poetic reflections resonate in contemporary landscapes connected to his story in a dense choreography of images, sounds and spoken texts about isolation and power, work and ageing, and the possibilities of social participation and change. "People say that the social standards of a country can be understood by looking inside their prisons—that a prison is a mirror that reflects society. This is an extremely supervised society. (Toshihiko Kamata, 1999)
