Documentary following a loggerhead turtle as she journeys across the Pacific. On the way she meets dolphins and whales, sharks and giant squids, typhoons and fishermen. She swims over deep canyons, and uses underwater mountaintops 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.
