The Longest Visit - S4.E4

Alan Finlay is a poor sailor. So when he is called out to visit old Strachan, the lighthouse keeper, who has spiked his finger, he dreads the trip. But Strachan is far worse than anticipated and Finlay must be both doctor and nurse - cooped up with Strachan and two other keepers in a spot cut off by gales from the outside world. Dr. Cameron is equally displeased as he has to cope with both his own and his partner's work while the latter is stormbound.
