The fourth series begins with Paul and Bob taking a trip to North Uist in the Outer Hebrides to catch fresh sea trout. The intricate network of tidal pools and sea lochs make the island near enough equal parts land and water.
Paul and Bob accept a special invitation to fish the estate lake at Burghley House, which sits on the border of Cambridgeshire and Lincolnshire. Their target is the bream, but who knows what they might catch in this rarely fished water.
This time Bob gets to choose the location of their next fishing trip, and takes a trip down memory by opting for the Lake District. This was where he used to come on camping holidays with his mates in the 1970s.
Bob, Paul and Ted are in Powys, Mid Wales, to catch wild carp. Locations include a hill top glacial lake and the river Wye. They meet with Mick May and Marina Gibson of the charity Cancer and Pisces, a cancer charity offering fishing as therapeutic respite.
Bob and Paul are on the River Severn, Worcestershire to catch the predatory zander. Bob has booked their overnight accommodation on the lightship SULA moored at the Gloucester docks. They visit Shinn's tackle shop and have a riverside lunch with local actor Charlie Cooper, star of This Country, and Ted.
