Overview:A loggerhead turtle journeys across the Pacific, meeting dolphins and whales, sharks and giant squids, and typhoons and fishermen along the way. She swims over deep canyons, and uses underwater mountain tops like motorway service stations. Blue whales thunder by like juggernauts, and sharks dance a beautiful midnight ballet around her. Pacific means peaceful, but it is clearly not. One minute she is under fire from marlin, the next swimming over a coral reef, with crocodiles as well as sharks.
