The Jaguar is South America's most mysterious predator - so secretive that even the scientists who study them can expect only a handful of sightings in a lifetime of research. Filming jaguars in the wild will be the greatest challenge yet for Big Cat specialists Owen Newman and Amanda Barrett. Equipped with amphibious buggies they head for Brazil's Pantanal, the world's biggest wetland, where jaguars feast on Caiman, Peccaries, Capybara and occasionally cattle. Deep in the wilderness, as the cameras begin to reveal remarkable new behavior, the film makers start to wonder just who is stalking whom.
