The Heroes of Telemark plot
"Unarmed and outnumbered, they stunned the world with their incredible victory."
In the autumn of 1942, the Norwegian resistance movement, supported by the English, plans a sabotage action against Norsk Hydro, a power station in Telemark, in central Norway. This installation is vital for the Germans because it produces heavy water for making an atomic bomb. Air raids prove ineffective. When it becomes known that the Germans are going to transfer the entire stock of heavy water by ferry, this seems to be the only way to prevent the Germans from having the material to produce an atomic bomb.
