The islands' new crop of junior doctors arrives in Shetland - this episode follows their first days and sees how they adjust to a very different type of medicine from what they are used to. Junior and newcomer Dr Wilson is thrown in at the deep end with two serious cases that arrive simultaneously into Accident and Emergency. Dr Wilson must use all his skills and rely on the vast experience of Shetland's native nursing staff if he is to provide the care the NHS expects. Away from the hospital, a doctor is working on Unst - the most northerly practice in the United Kingdom. And two of the new junior doctors take to the water to try out a popular Shetland hobby.
