"The movie takes place in the 50's Russia and the plot is about an idealistic pro-Stalin security officer who decides to investigate a series of child murders in a country where this sort of crime doesn't exist," Ekstrand explained. "He gets demoted and exiled but decides, with just the help of his wife, to continue pursuing the murderer. So we decided not to go with any electronic elements and only work with acoustic instruments and sparingly with effects. We also wanted solo viola and balalaika tremolo beds to be a part of the score so that the overarching tone would be very dark and ominous."
"The key scene for me was the first scene where we see the murderer on the train tracks with the boy," said Ekstrand. "It really told me how dark we could go with the rest of the score and also because it's a really strong scene as well as the first presentation of the motivating evil in the picture."
