The Tatars are here

A young boy peeks from behind a dark curtain, then the scene cuts to a woman in period clothing looking alarmed as she and others react to the arrival of Tatars, followed by a man in a black robe shouting with arms raised, then a blurry shot of a crowd, and finally a man in a black robe speaking from a pulpit. The setting appears to be a historical or period drama, with characters in old-fashioned clothing reacting to an external threat.
