Together with their new shepherdess, Rebecca, the sheep of Glennkill move into their winter quarters in the shadow of a French chateau. But their new home is far from idyllic. A number of sheep from a previous flock have disappeared, and deer are dying unnatural deaths in the forest. The strange goats from the neighboring pasture have a theory: a werewolf. With the help of the goats, they follow the werewolf's trail in a desperate attempt to save both themselves and Rebecca with sheep logic, courage, and woolpower.
