The Czech film avant-garde. A unique artistic direction of the 1920s and 1930s with great persons of Czech culture like Vitezslav Nezval, Jaroslav Seifert, Alexander Hackenschmied, Jan Kucera and many others being mentioned. However, is it really a forgotten landmark of the Czech cinematography or an artificial construct, created subsequently by film history? A one-hour science documentary by Libor Nemeskal about the films that 'perish and die when exposed to the daylight'.
