Julian and the team are in Walsall where they visit Joan Lockley who runs her very own ‘Hedgehog Hosprickal’. They are able to track the progress of one of Jo’s precious patients after he is released back into the wild and she is left feeling overwhelmed with emotion at the prospect of tracking her hedgehog’s movements. They then pay a visit to Lichfield to meet Kate MacRae who captures the activity of our feathered friends, with numerous cameras placed around her garden and inside her bird boxes, which she streams onto the Internet. After making his way to Stowe Maries, Julian talks to Russell Savoury and turns his attention to the water vole, a creature that is quickly disappearing due to reintroduced mink and loss of habitat.

Julian travels to the Farne Islands with Ben Burville where it is time for a costume change as he puts on a wetsuit. He then gets the chance to swim with the largest carnivorous mammal in Britain, an experience that certainly gets the star’s seal of approval. He then makes his way to Northwich in Cheshire to meet Dave Culley, who reignited his childhood passion for wildlife following a couple of life-changing motorcycle accidents. Julian then visits Hazel Ryan in Herne Bay where he comes face to face with the super sleepy dormouse.

Julian meets a woman who takes care of thousands of injured hedgehogs and helps her check up on a former patient. He also uses cameras that can see by moonlight to help a woman who streams footage from her garden on the internet to observe an elusive family of badgers, and takes two `otter spotters' to visit a unique sanctuary.
