Bob begins a titanic battle of wills with the newest member, Christine, for the heart and soul of his treasured walking group. She is freshly arrived from Barnstaple, exiled for a rambling crime she won't speak about. Christine's got a GPS and a lot of state-of-the-art hiking socks; technophobic Bob quickly marks her out as a nemesis in breathable fabrics.

Meanwhile, Bob's teenage daughter Hazel is mortified at the arrival of geeky Victor from her school. Then there is married couple Joe and Sophie. She comes on these walks to relax, but they do tend to get a bit stressful, and now Sophie's looking for another release in her life - which might be Victor.

As the lives of the walkers intertwine, they must face perhaps the greatest horror lurking in the British countryside - the previously cosy village pub which has "gone gastro". How will the group be able to afford lunch at £20 for a main meal, and will the tensions blow Bob's precious group apart for ever?
