In Faroese it's called a grindadrap-a "drive hunt" in which dozens of long-finned pilot whales are surrounded, forced into shallow water, hooked through their blow holes, and partially beheaded. While usually non-commercial, the grindadrap does provide food for local communities, but many if not most outsiders see it as cruel, unnecessary, and ecologically unsound. This program contrasts the traditional whaling practices of Faroese islanders with the rescue work of New Zealand activists who try to guide pods of stranded cetaceans back to the open sea. Both behaviors are examined, but the story's real heroes are the whales themselves. Viewers learn how the animals communicate, cooperate, display intelligence, and establish communities and social structures-facts that tend to support robust protection of the species.
