Twilight Zone Episode 8 - Time Enough at Last
ORIGINALLY BROADCAST November 1959
SUMMARY: Henry Bemis, a bookish bank clerk, can't find enough time to read. He reads constantly, nearly every waking minute. On his lunch hour, he reads of the H-bomb while down in the vault of the bank. It goes off suddenly, leaving him as the last man on Earth. In the ruins of a sporting goods store he finds a gun and considers doing away with himself … but when he catches sight of the remains of a public library, he has a reason to stay alive.
