Patrick O'Neal stars as Harmon Gordon, who is an aging man recently married to a much younger woman named Flora(played by Ruta Lee). Harmon is charmed by her beauty, but blind to her heartless, gold-digging true nature. By coincidence, his brother(played by Walter Brooke) is a scientist working on a youth rejuvenation serum that has had mixed results so far, but a desperate Harmon insists on being the first human subject, but the effects of the serum go much farther than he planned... Good cast here makes it watchable, but episode is still thin, and leaves several unanswered questions by its assumed "just" ending, such as if it really turned out best for Harmon...
