The insane and horrific history of the development of nuclear weapons is examined first-hand in Trinity and Beyond. The film makes use of extensive archive footage from declassified military sources, where the sources themselves speak about the development of nuclear weapons, revealing the calamitous results of use. From the United States's Trinity test of 1945, to the bombing of Hiroshima and Nagasaki; to the rapid increase in testing and proliferation by states across the globe, culminating to the first Chinese atomic bomb test in 1964, Trinity and Beyond is a stark reminder of this culture's insanity and death urge, and how—unless it is stopped—the expanding threat it continues to pose draws in, literally, the prospect of life on this planet for generations to come.
