 A look at Alfred Hitchcock s films. The Master of Suspense himself, who is interviewed extensively here, shares stories including his deep-seated fear of policemen, elaborates on the difference between shock and suspense, defines the meaning of "MacGuffin," and discusses his use of storyboarding in designing a film. Clips from many of his greatest films (including "North by Northwest", "Shadow of a Doubt", "The Birds", and the legendary shower scene from "Psycho") illustrate his points, often to Hitchcock s own voice-over observations, with narrator Cliff Robertson offering other critical insights.
