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.
