It's Christmas, and preparations are underway for the traditional nativity, with Ventress as Santa. Greengrass is busy selling geese to the locals. But when he sends David off to collect more, a snowstorm strands him, Bellamy and Ventress in the middle of nowhere and causes a bus filled with elderly people to crash. On the other side of the village, Nick and Jo have their hands full with a plane crash, a pregnant woman who goes into labour and a fugitive.
