Fern delves into the historic regions of Cornwall known as "hundreds", beginning her odyssey at Halton Quay on the banks of the River Tamar, at a spot where she believes she once saw a family of "piskeys" - mischievous creatures of ancient folklore. She then travels across Bodmin Moor, visits Tintagel Castle and takes in the sights and sounds of the historic 'Obby 'Oss celebrations.
