Travelling to incredible locations renowned for their fishing potential, Robson Green flies thousands of miles across the globe to be in the right place, with the right fishing guides, at exactly the right time. But even then, it's not going to be easy. Thunderstorms, drought, high winds and flash floods all have their part to play, and Robson will have to use every ounce of his fishing know-how, combined with the local guides and legends, if he wants to hook into the Ultimate Catch.

Fishing for huge predators from the mid-Atlantic, to hunting from a canoe in a lush volcanic crater, sight-casting on mysterious rivers in deep jungles, and learning local techniques from indigenous fishermen; he'll be hunting down migratory giants, netting huge crabs, and free-diving for a shape-shifting octopus. Having travelled thousands of miles across the globe, and picked his perfect moment, will Robson be able to pull it off?
