Guardian of the Light (2018)

After the end of World War II, young Kazakh soldier saves an old German civilian from death. The old man gives him a bag with the most valuable thing that he has - a portable projector and some films. 30 years later the former soldier becomes a legendary figure. He travels to small distant villages and pastures to show films. But professional cinema theaters come to big and small cities replacing the soldier who moves to more remote villages.
