School teacher Christian Kestner has all but forgotten his stay in Tbilisi, Georgia, seven years ago. When he receives a letter from David Ninochvili announcing his visit to Germany, he begins to worry. Why is David coming? To seek revenge from Christian, who once flirted with his wife? And what are his ties to the different factions vying for the control of Georgia? Christian becomes intensely suspicious of his unwelcome guest and his secretive ways. Fear turns into panic, so corrosive that it can transform even the most rational individual into a monster.
