The five anglers head to Costa Rica to explore the Pacific Ocean and come face to face with some of the most incredible fish in the world. Fishing close to shore off the tip of the Osa Peninsula, the anglers seek out the fast and furious roosterfish and learn to lasso handlines like the locals in the rough surf, before heading offshore to seek the fastest fish in the world - the sailfish. The anglers have just one day to catch and tag this incredible fish, but things don't go quite according to plan. Matt Hayes adjudicates alongside local fishing expert Todd Staley, who has led the way in fish conservation in Costa Rica. Between them they must decide which angler to send home, whilst the rest make it through to the semi-final.
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.
