In Greenland, Robson Green catches redfish and is shown how to cook it by his opponent, he takes part in a colossal `Cod-fest', charms an Arctic char from under a rock by tickling it and fishes for Greenland shark.

Robson ventures across the Atlantic to eastern Canada, where he attempts to catch his biggest ever Atlantic salmon, his biggest ever tuna and his biggest fish ever on the fly. On Prince Edward Island, he goes after bluefin tuna.
