Alfred Hitchcock's screen version of Frederick Knott's stage hit DIAL M FOR MURDER is a tasty blend of elegance and suspense casting Grace Kelly, Ray Milland and Robert Cummings as the points of a romantic triangle. Kelly loves Cummings; her husband, Milland, plots her murder. But when he dials a Mayfair exchange to set the plot in motion, his right number gets the wrong answer - and gleaming scissors become a deadly weapon. Dial "M" for the Master of Suspense at his most stylish.
