In this episode Paul travels to Cumbria in Northwest England to fish the Lowther and the Eamont, tributaries which feed the famous river Eden. It's late May and although the Eden does have a spring show of salmon, the main run isn't until the autumn, so he's going to target wild Brown trout and Grayling. To help him, he teams up with local expert and international fly fishing champion Andrew Dickson. So as well as being guided into some of the beautiful local brownies, Paul also gets a lesson in high speed competition fly fishing.
