With some of the biggest teeth of any freshwater fish, its ferocity is the stuff of nightmares. This mysterious monster predator pushes Jeremy to his physical and mental limit. It is going to take all of his skills and some supernatural help from the local witch doctor to catch one.

Jeremy Wade heads to The Mekong River in Thailand in search of one of the world's largest and most terrifying river fish - the Giant Freshwater Stingray. Armed with a venomous ten-inch barb on the end of its whip-like tail, this mysterious 700-pound predator tests Jeremy to his physical limit, snapping his heavy duty rod, tearing the muscle in his bicep, and luring him into a confrontation with the border police. In this epic quest, Wade witnesses a remarkable event in the life of one of these River Monsters and sheds some light on the natural history of this most elusive of monsters.

Angler Jeremy Wade is in for another nerve-testing encounter of the scaly kind as he homes in on a Far Eastern predator that's now invading America's backyards. Accused of homicide, and said to breathe air and crawl on land, the Snakehead is a monster that sounds more like a gangster than a fish. But does it deserve its 'Jack the Ripper' reputation? Is it really capable of killing a human? And what lies in wait for Jeremy when he ditches his rod and swims into the lair of the beast?

Jeremy Wade travels to one of the few rivers left on the planet that will still test a fisherman - the Congo. He is on the trail of a terrifying legend - the spirit Mami Wata, which is said to lure fishermen from their boats, taking them to the bottom of the river where they are imprisoned for eternity. It sounds far-fetched, but Jeremy soon discovers that the truth is every bit as frightening as the myth.

Extreme angler and biologist Jeremy Wade goes deep into the forbidding Alaskan wilderness. There are two large lakes here where legend has it that people have been vanishing without trace for hundreds of years. Jeremy cannot resist a challenge and is intrigued to see if there is a native species of lake monster that has actually been pulling fishermen into the icy depths. This is new territory for Jeremy who has never actually done any sub-arctic fishing before. Thankfully he doesn't fall victim to the frozen waters, or get eaten alive by a huge creature from the depths, but he does land probably the largest fish he has ever caught. Naturally our intrepid angler will be wondering if this is the fish of legend that has been dragging fisherman to an icy grave for centuries.

Jeremy Wade is on a quest to Africa's Rift Valley, the cradle of mankind, to explore the roots of fishing and the monsters these first fishermen would have faced. Fishermen here have one of the most dangerous jobs in existence. Storms come out of no-where, giant crocs attack from beneath, hippos maul you to death, and rival fishing gangs will kill you for your catch. But at the heart of this lurks a fish that can measure over 8ft long and weigh over 500lbs - the Nile Perch. This is a place where myth and reality merge, and it could be Jeremy's most dangerous mission yet.
