Composer Stephen Sondheim (Sweeney Todd, Into the Woods) and actor Anthony Perkins (Psycho) wrote this witty, complex thriller directed by Herbert Ross (Steel Magnolias, The Goodbye Girl). A movie kingpin (James Coburn), whose wife, Sheila, was killed by a hit-and-run driver a year before, hosts a cruise aboard his sleek yacht. His guests (James Mason, Raquel Welch, Dyan Cannon, Richard Benjamin, Joan Hackett and Ian McShane) are all friends (and some lovers) who may know more about Sheila's death than they're letting on. An elaborate murder game with Mediterranean ports of call is the itinerary. What unfolds is a mystery so intriguing, so cleverly plotted, even the title is a clue!
