The narrator explains to us that scientists have traveled to Arkanar, a planet still stuck in the middle ages. The society is regressing and the inhabitants have begun to murder all the intelligentsia, but the scientists are told not to intervene. Sort of like the Prime Directive. After the opening remarks, and aside from a few quips, we move permanently out of the realm of science fiction and into the world that has been created for us as we follow Don Rumata, a scientist disguised as a nobleman, as he wades through this world. And what a world it is. Mud, feces, grease, bile, and blood, are caked on to absolutely everything. Probably one of the greatest works of set design ever. With the roaming camera, it's as if the audience is a part of this diseased world, hopelessly regressing into its vile heart.
Unfortunately, there's a disappointing amount incoherence to the whole narrative. Most scenes would be over before you could piece together what had happened, and then only vaguely at that. The vision, however, of the world that Aleksei German has imagined, is totally unique and inimitable.
