In the heady days of the 1968 Prague Spring, a group of Czechoslovak Radio journalists risk not just their careers but their lives to distribute independent news amidst national and regional tumult. Orphaned brothers Tomáš and Pája are caught in the struggle for freedom. The elder, Tomáš, is a radio technician working at the station committed to defying the Communist Party’s censorship, overwhelming propaganda, and police harassment. When security forces pressure him to spy for them, Tomáš finds himself in a bind where he has to choose between betraying his colleagues or protecting Pája.
