In 1940, a man becomes a hermit after rejection. By 1950, a plague kills all post-pubescent males except him. Now desired by millions of women, he still yearns for his initial love interest, making him a treasured last man.

In the future year of 1940, a young man is rejected and humiliated by a girl and goes off to be a hermit in a redwood forest. By 1950, a dreadful plague of "Masculitis" has killed every male over the age of puberty but our hermit hero. He's become a national treasure, and millions of man-starved females crave him, yet he still wants the gal who wouldn't have him.—WesternOne

When Elmer Smith's proposal of marriage is refused by Hattie, his childhood sweetheart, he seeks seclusion in the forest as a hermit. Sometime later (1940), an epidemic of "masculitis" kills all the males in the world over the age of 14 with the single exception of Elmer. When he is discovered by Gertie, in 1950, a woman gangster on the run, he is taken to Washington and sold to the Government for $10 million. Two senators--the ladies from Virginia and California--then fight it out with boxing gloves in the U. S. Senate chamber to decide who will get Elmer as a husband. Hattie attends the fight, and Elmer--seeing her--rushes to her, claims her for his own, and marries her. A year later, twins are born to them, ensuring the continuation of the human race.
