The documentary film uncovers the story of Mašín brothers, which is of the greatest stories of the Cold War. A group of five young men decided to leave the then-communist Czechoslovakia with guns in hand to join the fighting in the then expected war between the West and the East. The year was 1953, and today, through the last witnesses, we follow the 30-day dramatic journey to West Berlin and the subsequent fateful events that happened to her loved ones at home.
