Shaun's seasonal excitement turns to dismay when a farmhouse raid to get bigger stockings for the Flock inadvertently leads to Timmy going missing. Can Shaun get Timmy back before he becomes someone else's present?

When Shaun decides to take the day off and have some fun, he gets a little more action than he bargained for. A mix up with the Farmer, a caravan and a very steep hill lead them all to the Big City and it's up to Shaun and the flock to return everyone safely to the green grass of home.
