Paul and Bob venture from London to the Scottish Highlands, taking a sleeper train overnight to their destination. They wake in the stunning vista of north west Scotland, where the pine forests and snow-topped mountains almost take their breath away.

They are on a quest to fish for ferox trout, which is a tall order for any angler. But they are in the right place, the River Garry, with a local guide to help them target their quarry.

Setting off in a boat, the pair fish long and hard, while also taking time to look for the Loch Ness monster.

Paul and Bob travel to the heart of the English countryside to fish a lake deep in the Surrey Hills, an Area of Outstanding Natural Beauty. They hope to catch some carp and barbel - but will Bob's clumsiness stop them from catching these skittish fish? The two of them settle in for a chat about the joys of gardening, much to Paul's dismay.

Later on, health expert Dr Anand Patel joins them by the lake. He and Bob dive straight into the importance of men looking after their health - especially their weight and particularly as they grow older.
