Nails

Set among the grey concrete apartment buildings of a run-down and soulless town in Eastern Siberia, a mentally tortured assassin for the Russian government becomes disenchanted with life as a killer. He retires to his seedy apartment and, hearing voices in his head, he decides to experiment with trepanation. By drilling holes in his skull, he hopes to be able to see beyond the veil of everyday reality, a reality he can no longer endure. With each nail he drives into his skull, he gets ever closer to the demons on the other side. What awaits him is pure insanity and has awful consequences for himself and those around him.
