Robson’s journey begins in the dead of night, at RAF Brize Norton. Only from here can he reach his first destination; a tiny outpost in the middle of the Atlantic Ocean and the most remote place Robson has ever fished – Ascension Island. There’s less than a thousand people here at any one time and, with its underfished waters, it promises Robson the fishing of his life. Here, he gets the chance to go after his biggest ever fish; the Six Gill Shark. This prehistoric beast grows to well above 500 kilograms and Robson feels every bit of it as he tries to reel it in. Ascension Island is teeming with fish, so just about every local is handy with a rod and line. The unspoilt waters also give him a chance to go totally old school, wading into the sea to try and catch one of the local Triggerfish with his bare hands. And, he’ll go out with local fisherman Noddy, who is assuring him of a fish fest like he’s never experienced. After only an hour on the water, Robson’s exhausted, and back at shore they need a crane to bring in the catch.
