Plot summary
"Hell-Fire" is an extremely short story, and deals with a journalist, Alvin Horner, who speaks with Joseph Vincenzo, a scientist at Los Alamos, at the first exhibition of a film with super-slow-motion footage of a nuclear explosion, with the footage "divided into billionth-second snaps." Vincenzo is sure that nuclear bombs are hell-fire, and tells the journalist they shall ultimately destroy mankind.

After the scientist's observations, the film starts. For a brief moment, before initiating the full reaction into the infamous nuclear toadstool, the atomic blast resembles a specific shape: the face of the Devil.
