Robson is heading into Brazil's wild and wonderful region of Mato Grosso, on the hunt for the Wolf fish of the Amazon basin. From the world's largest wetland to an Amazonian river that runs crystal clear, the landscape is stunning and diverse just like the people Robson has traveled over 6,000 miles to fish with. Robson will meet local fishing legends, a young up-and-coming angler, and spend time with an indigenous Brazilian tribe. Each stop will take him one step closer to his Ultimate Catch: the mighty Wolf fish, the air-breathing ambush assassin of the Amazon, and one of the most amazing fish he has ever tried to catch. Robson has come to Brazil for the best freshwater fishing on earth, but will he conquer?
