The movie Jaws scared an entire generation off of ocean beaches...but there are monsters lurking in freshwater lakes and rivers too. Are these just fish stories or are they real? From the Artic Circle to the Amazon, MonsterQuest will launch expeditions to find the biggest and nastiest giant fresh water fish. From catfish large enough to swallow kids whole to trout as large as a boat. Scientists will deploy giant lures and underwater cameras in a search for monster fish.
