Matt Baker and Anita Rani visit the ancient village of Bamburgh in Northumberland. Adam Henson and Robert Llewellyn find out how green farming machines measure up to traditional diesel.

Special guest Mary Berry reveals how farming and the countryside have influenced her life and career – and still do. Matt Baker is by her side to discover what inspired her during her childhood on her parents' smallholding and the rural issues she holds dear today. Mary is a champion of small producers and local produce, but she loves her pigs too. Adam Henson is despatched to investigate the state of British pig farming, while Anita visits a school with a field-to-fork ethos. This is music to Mary's ears, and something she would love to see rolled out across more schools across the country. And how will Matt fare when he has to cook for the UK's queen of the kitchen?
