The 12-year-old Ulja is smart and passionate about everything that has to do with space and science. When she discovers an asteroid that will soon arrive on Earth, she is very excited.

The asteroid is due to hit there soon. But Ulya's disappearance does not go unnoticed. Her entire family and the community are following her.
