This episode sees one of Britain's biggest open water swimming events, The Great North Swim, facing trouble as thick early morning fog descends on the Lake District. Plus we go out with the dogs who are trained to help in search and rescue operations on the fells, and a couple return to the scene of their first romantic weekend away 18 years ago in order to get married.
