The Vampires of Midland (Seasons 1–3)

Grandpa Slava is the oldest of the Midland vampire family. They live quietly. They live by the law. They live the unremarkable life of an ordinary Russian family and they never kill humans – ever. Although, of course, everyone knows they drink blood. And when some lifeless corpses are found in a birch grove near Smolensk... their peaceful life falls under threat.
