As 1970 dawns Jack, brother Nick and his family set off from swinging London to fulfil their dream of living off the land in the wild unforgiving hills of North Wales. They know nothing of farming or what battles lie ahead with the weather and their neighbours, or the ingenuity needed to survive. But armed with the Farmer's Weekly and protected by their youthful idealism and sense of the ridiculous they begin their adventure.

Peaks and Troughs is a warm-hearted, humorous and inspirational tale of life in all its drama – birth, death, tragedy, comedy, disappointment and hope – with the star player being one Rattlerow King David the 57th, a prize boar whose prodigious sex drive literally saves Nick's bacon.
