A landmark collective work in which a dozen directors and cinematographers from Krátky Film documented the turbulent socio-political developments from the winter of 1967/68 to April 1968 — the reform process known as the Prague Spring. The documentary is composed of surveys, discussions, speeches, compelling statements to the camera, and archival footage. Among the figures featured are prominent cultural personalities, writers, journalists, and politicians: Pavel Kohout, Anton Hykisch, Roman Kaliský, Gustáv Husák, Eugen Löbl, Ladislav Novomeský, Marie Švermová, Daniel Okáli, Ladislav Holdoš, Alexander Dubček, and others. The individual thematic sections are interspersed with music clips by the band Prúdy, filmed in well-known Bratislava outdoor locations.
