In this episode, a scientist gives his brother an experimental youth serum in order to save his marriage to a much younger woman.
This happens to be the Twilight Zone.Harmon Gordon, a wealthy old man married to a much younger woman named Flora, is exhausted by his wife's youthful and selfish lifestyle.
Raymond firmly refuses at first, saying that the serum has had mixed results with laboratory animals and will not be ready for human trials without decades of refinement.
Finding a stroke of poetic justice in what has happened, Raymond points out that by the time Harmon has regained adulthood, his position with Flora will be reversed, with her being old.
Ask her any day of the ensuing weeks of her life, as she takes notes during the coming years and realizes that the worm has turned: youth has taken over.
Disturbed by the character's willingness to experiment on a fellow human (Harmon, his brother), CBS asked that his occupation be changed to that of a research scientist.
