Matt Baker and Charlotte Smith pay the first of two visits to Jersey, where they find out about the agile frog that is capable of leaping up to two metres but is on the brink of extinction on this Channel Island. Matt mucks in on an organic farm producing exotic fruit and vegetables for the Durrell Wildlife Conservation Trust, with a little help from what comes naturally, while Charlotte explores how the brutal landmarks of German occupation are being repurposed to boost the local economy. Meanwhile, Adam is in search of a new sheepdog pup to take over from his faithful companion Peg, who is nearing retirement, and Tom investigates the potential impact on rural communities of plans to double nuclear capacity within 30 years.
