Matt, Anita and Adam discover the wonders of the Humber Estuary, a region famed for its bustling port and industry that is also home to diverse wildlife. Matt visits Far Ings Nature Reserve, where he helps manage a habitat for the rare bittern bird. Adam meets a farmer and butcher working in harmony with nature, while Anita heads to Blacktoft Sands to assist with a bird count and encounters a herd of wild konik ponies grazing in the reeds. Away from the Humber, Adam travels to Derbyshire to meet a young farmer transforming a traditional family dairy farm into a modern, thriving business.
