Physicist Robert Greeler uses laser beams, prisms, and pictures drawn by Descartes to explain the principles by which rays of light bend to form rainbows. While doing so, he teaches the viewer to understand and to look for more than the familiar bands of colors found in these phenomena. He concludes with the story of his own successful discovery of the invisible infrared rainbow whose existence he inferred and then set out to capture on film.
