The film begins in black-and-white and in standard 4:3 aspect ratio, as travel writer and newscaster Lowell Thomas appears on screen to discuss the evolution of motion picture entertainment, from the earliest cave paintings designed to suggest movement, up to the introduction of color and sound. At the conclusion of the 12-minute lecture, Thomas speaks the words "This is Cinerama" and the screen expands into the full Cinerama aspect ratio and colour as a series of vignettes, narrated by Thomas begin.
