Matt Baker and Ellie Harrison experience the bracing mix of sandy beaches and remote heathland that make up much of the Suffolk coastline. Matt heads to the seaside town of Southwold to help spruce up the famous beach huts. Ellie is further inland, exploring the old industrial waterways which now inspire a host of artists. Tom Heap is on the opposite side of the country, finding out why we are still digging up one of our greatest natural defences against climate change, peat. Meanwhile, Adam Henson pays tribute to an extraordinary race horse.
