The movie opens with a British nuclear submarine called the HMS Nereid entering Tokyo Bay in the then-future of December 1983. The ship’s crew and Japanese seismologist Yoshizumi (Masao Kusakari) send a reconnaissance drone to search the city for any survivors, only to find decayed bodies. It also gathers air samples of something called MM88.
A Day Called ‘X’ was a dramatized CBS documentary set in Portland, Oregon in which the entire city is evacuated in anticipation of a nuclear air raid, after Soviet bombers had been detected by radar stations to the north; it details the activation of the city’s civil defense protocols and leads up to the moment before the attack (the ending is left intentionally unknown).
Glenn Ford stars as an American paratrooper GI who travels to France after the end of WWII to try and recover a jewel encrusted glove that had been stolen from a country church during the war. His quest leads him to a beautiful young tour guide (Geraldine Brooks), and a Nazi collaborator (George Macready) whom he had fought during the war. The movie was shot mostly on location in France and Monaco.
