After years of questioning why people fear him, Death takes on human form for three days so that he can mingle among mortals and find an answer. He finds a host in Duke Lambert after revealing himself and his intentions to the Duke, and takes up temporary residence in the Duke's villa. However, events soon spiral out of control as Death falls in love with the beautiful young Grazia. As he does so, Duke Lambert, the father of Grazia's mortal lover Corrado, begs him to give Grazia up and leave her among the living. Death must decide whether to seek his own happiness, or sacrifice it so that Grazia may live.
The film was an enormous critical success. Time called it "thoughtful and delicately morbid", while Mordaunt Hall for The New York Times wrote that "it is an impressive picture, each scene of which calls for close attention". Richard Watts, Jr, for the New York Herald Tribune, described it as "An interesting, frequently striking and occasionally beautiful dramatic fantasy", while the Chicago Daily Tribune said that March was "completely submerged in probably the greatest role he has ever played." Variety called it "the kind of story and picture that beckons the thinker, and for this reason is likely to have greater appeal among the intelligensia." It praised March's performance as "skillful". John Mosher of The New Yorker wrote that the film was "nicely done", although he suggested it was "a little obnoxious with all its talk of being in love with death." The film was a box-office disappointment for Paramount. The American Film Institute recognized the film with a nomination in its 2002 list, AFI's 100 Years...100 Passions.
Universal Studios, which acquired the rights to the film in 1962 following a merger with then-owners MCA, made a 1971 television production featuring Yvette Mimieux, Monte Markham, Myrna Loy, Melvyn Douglas and Bert Convy. Loy related in her biography that the production was marred by a decline in filming production standards; she described a frustrated Douglas storming off the set and returning to his home in New York when a tour guide interrupted the filming of one of his dramatic scenes to point out Rock Hudson's dressing room.
A May 2006 episode of the television dramaMedium also builds on the concept of death portrayed as a man. The season 2 episode is similarly called, "Death Takes a Policy."
