Emma's dad reads about the theft of a pig in the local paper and she wishes she could find it and claim the reward to pay for a new bridle for Sheltie. Instead she and Sheltie help Mr Brown, a local farmer, to earn some money. They're watching the sheep when Sheltie spots a smashed trailer hidden in the bushes, and they see two men camping in the woods. Emma and Sheltie are soon on the trail of the thieves and catch them stealing Mr Brown's new sheep. They raise the alarm and, in the nick of time, Sheltie discovers a stolen pony and a pig, as well as sheep.
