Ralph Roberts, a retired widower, begins to suffer from insomnia. As his condition worsens, Ralph begins to see things that are invisible and intangible to others: colorful manifestations of life-force surrounding people (auras), and diminutive white-coated beings he calls "little bald doctors", based on their appearance. Roberts perceives other planes of reality and their influence upon the "real" world. He finds that his sweetheart, Lois Chasse, is also a sufferer. They eventually discover that their insomnia has been induced by the two little bald doctors to help them defeat agents of the Crimson King.
