This video is a Cossack dance routine set to the track.  Martina is dressed in traditional Cossack costume, and sings while different Cossacks attempt to impress her with their dancing skills. 

The look of the film and the location is as if we’re really somewhere in Russia.  There could even be some occasional subtitled Russian dialogue over the track, with a simple story about different Cossack men competing for Martina’s attention.
