Nine members of an extremely rich and hateful family have decided to hold a reunion on a remote island in the Mediterranean. No sooner than their arrival do old grudges, resentments, and feuds begin to make themselves known, and with them allusions to some even more macabre events in their past. But when their boats are torched and the bodies begin to pile up, it becomes clear that someone is not willing to let old wounds heal. John Richardson (BLACK SUNDAY), five-time Oscar nominee Arthur Kennedy (LAWRENCE OF ARABIA), and Italian character actor Massimo Foschi (JUNGLE HOLOCAUST) star in this Agatha Christie-inspired giallo from prolific spaghetti western director Fernando Baldi.
