Letters from a Dead Man is another film that deals with the theme of the nuclear nightmare.
A history professor and several of his colleagues have survived in a fallout shelter beneath the museum where they used to work. The professor spends his time writing a series of letters to his son in the unlikely hope that he is still alive. Amid the surface devastation, the professor finds a group of children who have been struck catatonically mute by the holocaust. Though the city has been placed under rigid militia rule, he attempts to take them away to a place of safety.
