In 1957, the world was shocked by the Sputnik I mission, while in a private space station called Bert Tower, on the hills of Torino, Italy, two young brothers, Achille and Giovanni Battista Judica Cordiglia, were acting as forerunners of hacking: just with the help of their genius they recorded every radio signal from the space during the whole Cold War period. Space Hackers is an historical documentary based on their incredible private archive, made of unique audio-recordings and 8mm and 16mm films shot by the brothers themselves, and their funny and passionate story.
