Young television producer Michael Donovan tries to abandon his womanizing ways when he meets and marries elementary school teacher Katherine. Among his endearments to her is filming himself in his studio, costumed as "The Sandman," sitting on a makeshift moon with a starry background, and telling stories to entertain Katherine's class. When Michael's struggles to resist the near-irresistible temptations on his job lead to Katherine catching him in the act on the set, they separate. After his wise, and composed older brother Tommy helps him see how empty womanizing really is, Michael puts "The Sandman" to work in a bid to win Katherine back.
