Ascension Island, a remote Mid-Atlantic outpost famous for its big game fishing, is under siege. Tiger sharks, hammerheads, even great whites, lured here every year by the bountiful reefs, are displaying aggressive behavior, culminating in the island's first shark attacks in its history.

Herman Melville's epic ocean adventure "Moby Dick" is an American masterpiece. But was this stirring tale of violence and revenge simply an allegory, or were there real giants of the deep deliberately attacking whaling ships? With the help of centuries old witness accounts and modern day science, we explain how the legend of the great white whale came to be. Then we determine if the multiple sperm whale assaults on ships in the 19th century were indeed premeditated and coordinated.

Brazil's massive Pantanal is a land of extreme contrasts, ruled by dramatic cycles of torrential rain and arid heat. At the peak of the dry season, the floodplains bake and a searing struggle for life begins. However, there is an oasis that stubbornly refuses to disappear, a mysterious place that serves as a sanctuary for a host of animals and a hunting ground for predators.

It's home to some very rare species, including the drill -- one of the most endangered primates in the world. Join us on a jungle expedition as we uncover the secret life of these reclusive primates and track down the seasonal migration of the goby -- a plucky fish battling its way upriver past strong currents, deadly predators, and even a 100-foot waterfall, to reach the spawning grounds of its youth.

In the far reaches of the North, wolf and bear come head to head. Winter has been long. The melting ice reveal scattered carcasses in the Swamp: a feast worth fighting for.

Even 2,000 years after his death, General Hannibal's battle strategies are still studied today. But of all his military feats, perhaps his greatest was leading his massive Carthaginian army of men and three-dozen elephants across the Alps and into the heartland of Rome in 218 B.C. Until now, the route they took has been a matter of dispute, but thanks to modern-day technology, geomorphologist Bill Mahaney and microbiologist Chris Allen believe they've accurately traced this ancient journey.

In China's Valley of the Kings, there stands a tall, carved stone. It honors the resting place of a woman named Wu Zetian, who rose from concubine to become China's only female emperor.

Join the investigation as we revisit old evidence and reveal new truths, using artifacts and forensic tools to tell the true story of China's Emperor of Evil.
