A great white shark closes its massive jaws over the leg of a young swimmer. In the forested, delta villages of West Bengal in India, villagers live and work in a constant state of fear. Are animals everywhere – both in the wild and in captivity - participating in a dangerous trend? What is the line between predator and prey…hunter and hunted?

Fraser Island, Australia, March 29, 2001: Englishman David Eason vanishes from a group of sunbathers enjoying a guided tour of the island. Extensive rescue searches turn up no trace of the man. How could someone just disappear off the face of the earth? Just one month later, two boys, aged 9 and 7, are chased down and brutally mauled by a pair of dingoes, or Australian wild dogs. Then, in 2003, a solitary hiker makes a grisly discovery in a remote part of the island: the skull and bones of a human. Forensic experts identify them as the remains of David Eason. The investigators visit the attack scenes to examine the evidence and pursue the possibilities. Was Eason murdered? Did he commit suicide? Or die of natural causes? Or…could he possibly be the first fatality in the turf war between humans and dingoes on Fraser Island?

After seven decades of wary coexistence between bears and humans, a rash of attacks stuns the remote island of Kodiak, Alaska. Hunters and tourists are suddenly faced with what seems to be unusually aggressive bears. Despite evidence of a growing problem, heads don’t turn until one of these encounters becomes fatal. Within a span of 24 hours, two savvy outdoorsmen are attacked only a few miles apart – and only the man who violates all bear attack precautions lives to tell his tale. What is happening on Kodiak Island? Are the hunters becoming the hunted?

In West India, in the world’s largest delta, 54 small, forested islands make up the Sundarbans. It’s a perilous place buffeted by monsoons, soaked by extreme tides, and haunted by some of the most fearsome predators on the planet. The human inhabitants of the region seem to have struck a standing truce with these beasts. Bengal tigers habitually attack—and kill—30-50 people every year, and that’s just the reported number. They stalk men as they gather honey in the mangrove forest, spring upon fishermen as they ride the muddy swells of the rivers. Now, a tiger has chosen a new target—this time inside the village on Shamshernagar Island itself. What could have lured the striped cat into human territory? As the investigators probe the attack on young Rupali Baulia, they are forced to confront even bigger issues. Bengal tigers are protected in India, but should this protection be reconsidered?

Alligators are surging from waterways and ambushing people as they walk their dogs and landscape their yards. A team of biologists, trauma physicians, and detectives investigate this disturbing outbreak of violence, returning to the scenes of the attacks in search of hidden clues. The experts explore details of alligator behavior, shed light on the victims’ final moments, examine human encroachment issues and pull together previously hidden evidence in order to look at each incident more closely. As the pieces of the puzzle come together, they are confronted with a bigger picture that surrounds each tragic encounter between animals and humans.
