Born in the wild and majestic wilderness of Lapland, the little reindeer Ailo must set out with his herd on a dangerous journey through the frozen taiga, past imposing fjords and rugged mountains—a journey that will last an entire year. Every day brings surprises for Ailo, but also dangers. At his mother’s side, Ailo learns to survive and, as his herd migrates through wild Lapland, grows into a full-grown reindeer.
