Big dreamers and dreams have big. Even when you are a very small pony Elliot, you can go to being once in a harness for Santa Claus to his legendary deer. And here he really had a chance that could not be missed: Lightning, one of the old deer, decided to retire just before Christmas itself. Elliot has 3 days to prepare himself for the competition for a place in the harness. His rivals will be much stronger, faster and more powerful, but they do not have the main thing: dreams of delivering gifts to kids all over the world. The kid will do everything possible to achieve his goal.
