The film is a story of a mother and her son Lubos who lives in a world turned upside-down, or, arsy-versy. Lubos broke free from the world as generally conceived by others to arrive at the supreme human-nature symbiosis; he flew away to a planet purely inhabited by butterflies - intelligent beings. The sole focus of his life energy, enriched by a great deal of empathy, is being channelled into his amateur photography and film making, the climax of his fascination with natural phenomenon being his unique study of bats. By way of communicating with the upside-down creatures he is fascinated with, he attempts to achieve the utmost understanding between man and beast. He is assisted by his mother who has been a great research and life.
