The six anglers travel to their most remote destination yet - the mighty Mekong River in Laos. Here people fish for survival, not for sport. The anglers must battle the blistering heat and the ferocious currents of the widest rapids in the world. They will use traditional bamboo rods, throw themselves into the local way of throwing cast nets, and use all their own experience and sport fishing equipment to see if they can discover anything in the Mekong that the local methods cannot. Matt Hayes will be joined by Mr Mai, the headman of his village on Baan Hangkon Island, to judge which angler leaves the expedition whilst the rest journey on. The heat, the terrain and the simple equipment make this the toughest leg of the expedition yet.
Eight anglers embark on their first expedition to the wilderness of Iceland, where they brave extreme cold, wind and rain to fish in some of the most challenging conditions they have ever faced. In the north west, close to the Arctic Circle, the anglers fish from sea kayaks in the freezing fjord before learning to harvest cod using a traditional Icelandic technique. Further south, in a lake heated by volcanic vents, they fly-fish for some of the largest brown trout in the world. Matt Hayes is joined by local fishing expert Vala - she will help him judge which angler must leave the expedition whilst the rest journey on to the next location in their global expedition.
The seven anglers leave the freezing cold of Iceland for the tropical heat of Cuba - but violent storms make conditions tough. In the salt flats a couple of hours south of Havana, they chase the ghostly bonefish, and in the Bay of Pigs they must fish Cuban-style - on simple tyre tube boats. Finally, on the Atlantic coast they are after giant tarpon - the silver king. Matt Hayes is joined by local fishing guide Lazaro to help him judge which angler leaves the expedition whilst the rest journey on to the next location in their global expedition.
