Dick Strawbridge and his son James venture out from New House Farm in Cornwall to meet aspiring individuals and families who want to try and make their lives greener. Eco-campsite sisters Jake and Candy get their wind-turbine in Cornwall, but not before being tested by Dick on their knowledge of electricity. How do you insulate a centuries old cottage if you still want to enjoy the timber beams? In Lincolnshire, we meet Zannah and Arthur who discover that going green in a conservation area isn't easy. They've got their solar panel, but will they be allowed to keep it? In Somerset, we meet the Warrens, who with Dick's help start sustainable livestock farming when they get their first Gloucester Old Spot pigs.
