Katie Morag has two grannies - Grannie Island and Granma Mainland. The two grannies are as different as different can be. It's the day of the Isle of Struay Show with its main attraction, the Grand Struay Sheep Contest, and Grannie Island is trying to win the prize with her beloved sheep Alecina for the eighth year in a row. Neilly Beag, however, has high hopes that his own lovely ewe will take the cup.
