The Radiant explores the aftermath of March 11, 2011, when the Tohoku earthquake triggered a tsunami that killed many thousands and caused the partial meltdown of the Fukushima Daiichi nuclear power plant on the east coast of Japan. Burdened by the difficult task of representing the invisible aftermath of nuclear fallout, The Radiant travels through time and space to invoke the historical promises of nuclear energy and the threats of radiation that converge in Japan in the months immediately following the disaster.
