Germany invades Poland at the beginning of World War II and this historic event leads to the creation of the Polish Underground State - the largest resistance movement in all of Europe.
The Polish Underground State is waging a propaganda war, and its military intelligence is stealing Germany's greatest ballistic missile secrets. There is also a daring escape from Pawiak.
The courts of the underground state are working to ensure the safety of underground networks. Diversion activities are organized, and Polish elite units from England - Cichociemni - enter the action.
The Home Army continues the fight for the liberation of Poland. The Warsaw Uprising breaks out. Terror returns as Stalin occupies Eastern Europe. The war is over, but the Poles are still fighting.
