At the Gilbert Bain hospital on Shetland, nurses and doctors go the extra mile to care for any and all emergencies. Schoolboy Bruce runs too many miles and injures his leg. A football match leads to an awkward injury for teenager Saul, but a football tournament makes a great weekend for Dr Lalla and his family. An able seaman is referred by his ship's doctor, barely able to breathe. An unfortunate migraine sufferer develops worrying new symptoms which warrant a brain scan and an anxious overnight stay. And a young local man gets mud in his eye, presenting diagnostic difficulties for the night team in Britain's most remote Accident & Emergency unit.
