It's a tale of transformations as Matt Baker and Charlotte Smith head to the Norfolk-Suffolk border. Matt gets his fingers dirty gardening and feels the heat of the forge at a social enterprise that is harnessing the healing power of the rural landscape and training homeless people in traditional skills to give them a fresh start. Charlotte heads into the surrounding countryside to meet farmers making Britain's only raw brie, and she sets sail with a lady fisherman who swapped a job in logistics for lobsters and whelks. Adam Henson looks at how science is using biobanks to secure the future of rare breeds.
