Freya, a red-haired Viking girl with curly hair, and her small white dog Odin, go on a mountain adventure with the wise dragon Nils. They search for trolls and cross a desert.

While crossing the desert, they meet a friendly dragon and magical elves who guide them to the trolls' cave.

Inside the cave, they find the trolls but realize they're not scary at all. They become friends and enjoy a troll party.

On their way back, they encounter a majestic unicorn. It joins them and leads the way to a celebration in their village.

The village celebrates Freya's successful adventure with delicious food, music, and dancing.
