Prague, 1968. The International Editorial Office of Czechoslovak Radio is staffed by courageous journalists, celebrities of their time. Young Tomáš works amongst them, though it is his brother's dream job. Tomáš' main concern is keeping them both safe with no idea that the editors are being targeted by the Secret Service. When a recording is discovered and broadcasting it could change the fate of many, the Secret Service focuses even more intensely on the newsroom. Will Tomas go down in history alongside the journalists or will he protect his younger brother, the last remaining member of his family?
