The two young children Minik and Pani live with their parents on an iceberg island off the east coast of Greenland.

One day, their father tells us about a couple of enchanted rocks that can give unimaginable strength, and with this, the most important thing of all: the courage to spite one's own fears. The children's father teaches them an old magical song that adds to the ritual. Without it, the magic won't happen.

As they listen, the children look at each other and puff themselves up, because they are not afraid of anything. But their father calms them and says, that courage is not something that you own. It's something that is summoned in the very moment that you get scared, and you never know what might scare you. What's more, the two kindred stones must be rubbed together to provide the strength to withstand any kind of setback.

- We have to find the stones! We want to be as strong as a polar bear. Teach us, pappa! Teach us that song!

Dad teaches his children the words of the song, and suddenly, he scares them by making strange sounds and using a scare mask. But the kids just laugh!

- We told you, pappa, we are not afraid of anything!

- Well, that's all right, but if you do get scared, you now know the song. It will help you to think of more important things than being anxious, he reassures them.

- And, when you are afraid, the first step is to find your courage. Anyone who desires courage is able to sort out just about anything.

That night, the children stay awake and sneak out of the hut. After a challenging climb where they have to use all their skills and help each other up the rocky walls, they find the magic stones. They follow the instructions to rub them together and sing the song their father taught them, and they summon an enormous, ferocious, and furious polar bear. In protecting themselves they end up in a choreographed dance battle with the bear where, Minik stumbles into the open jaws of the bear and disappears into its belly. Pani decides to follow her brother to try to save him by fearlessly jumping into the bear's huge vicious mouth .

Inside the belly of the bear they are trying to think of a way to get out, and they soon realize that even bears must be ticklish. They use their small hands and fingers to tickle the bear from the inside, and the sound of his laugh makes icebergs collapse and avalanches come down, until the bear finally lets out a big fart.

And with a huge poof, the kids come flying out of the butt of the bear, and land all tangled up in the snow. After they finally get their arms and legs stretched out and their clothes put back on, arms and legs in place, they discover that their muscles have grown. Yes, it was indeed the increadible power of a polar bear!

They rush back towards home and their worried parents are shocked to find their children with all this muscle. But then, the lightest touch makes the children fall down and go to sleep and become light as feathers. So, the parents carry them back home to the hut and put them to bed.

Once back, their mother finds the kindred rocks that she believes gave the children the courage to defy their fear. As she looking to hide the rocks, we see that every stone on the ground gleams like the stars in the sky. So, wherever you go, you can find your courage and power within.

As the mother realizes this, she puts down the rocks, and starts dancing and singing a song of gratitude under the starlit sky.
