As produced by PBS and aired as an episode of the series Nature, this documentary follows the obstacle-filled course of a loggerhead turtle named Adelita, on her once-in-a-lifetime, 9,000 mile journey from Mexican shores to the beach in Japan where she first hatched from an egg. En route, Adelita must counter such potential setbacks as human fishing gear, the bloodthirsty rampaging of hammerhead sharks and underwater tempests. The said course, which took the turtle well over a decade to complete, gave scientists unprecedented insights into the way in which turtles use magnetic mapping to navigate their way across large distances - insights discussed at length in this program. ~ Nathan Southern, All Movie Guide
