Anchored by a man whose quest humanizes global changes, this film traces the historical events and present situation of nuclear disaster across human society. Every nuclear site he revisits represents a specific temporality - Fukushima, Japan, as the ongoing present; Semipalatinsk, Kazakhstan, as the concealed past; Chernobyl, Ukraine, as the forever alienated present, and Onkalo, Finland, as the future of the future. The narrative created through deconstruction and reconstruction of histories provides a new space to reflect on nuclear issues.
