Overview:The three finalists face their sixth country and their final frontier - Zambia. Navigating the immense Zambezi River, the anglers fish alongside wild animals on land and in the murky water. They search the croc-infested waters for huge vundu catfish, fish local style from wobbly dugout canoes and try to catch Africa's equivalent to the piranha - the tiger fish. They must use everything they have learnt across their worldwide expedition as the judges will be looking for which one of them is the complete angler. Matt Hayes is joined by Charles Tembo, who has grown up on the banks of the Zambezi, whilst Ben Fogle is with the anglers every step of the way on their final journey. The fish here have adapted to survive in these dangerous waters. The anglers have just one week to prove they have the courage - and the skills - to do the same.
