At last, Niko the reindeer's biggest dream is coming true! Together with his dad, he will be able to fly in Santa's elite Air Squadron. However, it soon turns out that there is another candidate to take his place - it's Stella, a giddy reindeer who is also eager to contribute to the distribution of Christmas presents. Despite the rivalry, the two like each other, and Niko, encouraged by his rival, shows her where Santa's famous sleigh is hidden. The night before Christmas Eve, it comes to light that Stella has taken the priceless vehicle without asking and fled with it towards the frigid North. Niko, together with his best friends Julius the squirrel and Wilma the weasel, set off on the trail of the fugitive. Christmas, which is just around the corner, depends on their mission! If everything is to work out, the young reindeer will have to learn how to be himself and make many non-obvious choices.
