Bulgarian flag waving in the wind on a stone structure, likely an old fortress, with mountains in the background under a blue sky. Initially, a man in a black jacket and light-colored pants is sitting on the stone structure. He then walks off to the left. Another person, wearing a yellow garment, briefly appears on the right side of the stone structure. The camera pans right, showing more of the mountainous landscape and the stone ruins. The sky has some clouds. The overall setting appears to be outdoors on a sunny day.
