A film journey through places near and far, real and dreamy, on the border between reality and fiction, where it is possible to learn how close the realm of the invisible lies and to contemplate whether it is possible to approach the invisible through film. Guides on this journey are various explorers who present their elusive experiences with researching and capturing imprints of the invisible – former filmmakers, a forgotten film movement, a local history expert, a mountaineer, a professor, and the director, Lea Petříková, herself. But the more they reveal, the more complicated it gets.
