In a little copse near the east coast main line of Yorkshire, in a house that Daddy built himself, live siblings Daniel and Cathy. They roam their wood, completely free of modern living conventions. They know Daddy sometimes has to go off and do hard work to get money, but what exactly he does never enters their minds. Then one day a local landowner shows up on their doorstep, and the modern world seems like crashing in on their happy existence.
