Is it possible to come to someone's dream and film it with a camera? It is a dream so all sounds are fading, and you can only partly hear the words. The dream has no real end and no beginning. There are two girls, Lena and Katya, and 10 dreams: 5 Lena's dreams and 5 Katya's dreams. Two worlds meet in a place where the rules of material world don't seem to work.
