The story of Czech pilots in RAF service during the Battle of Britain, and the ongoing aerial battle in Northern Europe. It tells the story of the crews of the RAF’s No. 311 Squadron, which was mainly crewed by escaped Czech airmen, and their bombing raids during the Second World War.

A personal and political biography of the Octopus, or the Prague National Library project, but also a biography of the last years of the life of the author of this design, Jan Kaplický, who wrote in his diary in 1998: to win the competition and have one love. With this entry, read by Eliška Kaplicky at the beginning of the film, it is as if the world-class Czech architect wrote not only the "script" for the final decade of his life, but also for a film that follows the dramatic social story of creative imagination and the intimate relationship between a man and a woman.
