Saw this and still don't know what its about...

I saw this and still have no idea what its about, although don't doubt me when I say that I love it. I have always loved animation, especially Russian. I think it's because its so varied and each film that I see keeps getting better and better. I found yukkimishima on youtube. Its one of the biggest accounts that I have came across that has so many Russian animated films. I really want to visit Russia one day, but first I must learn the language.
