Paul and Bob are on the River Severn in Worcestershire to fish for zander, and enlist the help of local guide Tim Maslen to find the best spots. As they sit and wait, they ruminate on the state of Britain's rivers in general, the threats that they are under and what it takes to do something to help them improve. After a few hours they move down the river to a secluded beach and meet their special guest - local actor and self-confessed fishing addict Charlie Cooper, star of This Country.
