13 May 1969, University of Tokyo. Eighteen months before Mishima Yukio died by seppuku, the literary giant took the stage at his alma mater for a scintillating debate that has attained legendary status. During the peak of student protests, the radical right-wing author engaged in an intense battle of words about politics, philosophy and the course of Japan with the Zenkyoto, the leftist student group that spearheaded the protest movement. Bringing us back to that momentous time of social unrest and ideological fervour, this documentary reveals rare restored footage of the historic debate filmed by TBS, as well as new interviews with those present at the debate.
