The video shows a large herd of reindeer being led by a person on horseback through a snowy forest. The reindeer are walking in a single file line, following the person on horseback who is leading them. The forest is covered in snow, and the trees are bare, indicating it is winter. The person on horseback is wearing a red jacket, which stands out against the white snow. The reindeer are mostly brown and white, and they move slowly through the snow.
