Paul and Bob travel to the picturesque River Usk in Wales, where Paul’s father first taught him to fish as a young child. Their quarry is the wild brown trout. They discuss their respective childhoods and reflect on their own family lives. In their cosy cottage accommodation in the heart of the countryside they compare school photographs and Paul serenades Bob with his guitar.

Paul and Bob brave the wild lakes of Essex in search of the mighty carp. They have the latest high-tech equipment and are fully prepared to stay all night if they have to, to catch the biggest fish they can. They discuss the true meaning of a mid-life crisis and decide to visit a beauty clinic to see if there are any suitable treatments available to re-capture their youth. Bob reveals his secret recipe to make the perfect scrambled eggs but it is not the only thing which shocks Paul in this episode.

Bob has harboured a childhood dream to catch a salmon so they set off for the River Tay in Scotland full of hope and excitement for this special trip. A ghillie guides them up the intimidating river in a boat and they fish using various methods to catch the elusive fish. They discuss luck and fate and the part it has played in their lives. They stay in the heart of the highlands, Bob cooks Paul a traditional Scottish breakfast and they set off for a swift round of golf before resuming their fishing. As the sun sets they reflect on their dreams – did they come true on this trip?

Paul and Bob fish for the predatory perch in the Upper Tamar Lakes on the Cornwall and Devon border. The following day, they embark on another fishing adventure, this time on the open sea.

The pair fly to Enniskillen, where they take to the waters of Loch Erne in their quest to land the mighty pike, which eluded them in series one. Plus, Paul demonstrates how to perform life-saving CPR.

For their final quest of the series, Paul and Bob take to the River Ure in the heart of the Yorkshire Dales, in search of grayling. After mulling over their plans for retirement, they meet the surgeon who performed Bob’s life-saving triple heart bypass.
