James Stewart, Farley Granger and John Dall star in this macabre spellbinder, which was inspired by a real-life case of murder. Two thrill-seeking friends (Granger and Dall) strangle a classmate and then hold a party for their victim's family and friends, serving refreshments on a buffet table fashioned from a trunk containing the lifeless body. When dinner conversation revolves around talk of the 'perfect murder', their former teacher (Stewart) becomes increasingly suspicious that his students have turned his intellectual theories into brutal reality.
