The story of a little loggerhead turtle, as she follows in the path of her ancestors on one of the most extraordinary journeys in the natural world. Born on a beach in Florida, she rides the Gulf Stream up towards the Arctic and ultimately swims around the entire North Atlantic across to Africa and back to the beach where she was born. But the odds are stacked against her; just one in ten thousand turtles survive the journey.

The program focuses on the hypothetical and scientifically feasible evolution of alien life on extrasolar planets, providing model examples of two different fictional worlds.
