Ireland in the middle of the 17th Century.
The country is being tyrannised by Cromwell's soldiers, but it isn't just the people of Ireland who are suffering - Cromwell has declared a war on wolves, and it won't be long until every last wolf is gone from the country. Una, a young brave girl, has an opportunity to stand up for that noble animal and to help one wolf evade the clutches of Cromwell's soldiers.
But what chance do one girl and one wolf have when the whole world is against them?
