Part 1: Target Peenemünde — In 1939, antifascist scientist Dr. Kummerow alerts the British consulate to a top-secret Nazi missile program in Peenemünde. When the English disregard the “Oslo Report,” the Germans continue their experiments while underground resistance groups from France, Poland and Germany attempt to locate the facility and stop the program themselves.

Part 2: Password Paperclip — The Allies’ belated response comes only after the first missile is launched and merely drives production underground. Scientist Grunwald, whose household suffered in the Allied attack, settles his moral conflict by joining the resistance. In the end, it is the brave workers at Peenemünde who manage to sabotage the program and disable the rockets.
