Director Nelly Ben Hayoun-Stépanian finds an unlikely companion in the late political theorist Hannah Arendt as she embarks on a world tour across sixteen cities—looking for the origins, mechanics and power dynamics behind knowledge. The film investigates the act of thinking in the twenty-first century as well as fears associated with it. It features a long list of some of the most interesting minds of our times: political activist Noam Chomsky, Pussy Riot’s Nadezhda Tolokonnikova, Arendt’s students: Arjun Appadurai, Leon Botstein and Richard Bernstein, Japanese Living National Treasures: Bunraku puppeteer Kanjuro Kiritake II, Kimono master Takayuki Takahashi, former Lord Mayor of Sheffield Magid Magid, and many more.
