The RAF's 633 Squadron is entrusted with a critical mission, one of utmost importance to the Allied invasion of France during World War II. Their objective is to obliterate a strategically significant German base located in Norway. This base is responsible for producing the fuel necessary for German rockets, posing a grave threat to the Allied cause.
The mission is nothing short of perilous. To reach the base, the squadron must execute daring and precise flying maneuvers. Moreover, they must contend with a formidable array of anti-aircraft batteries that pose a significant threat to their aircraft. To further complicate matters, the Norwegian Resistance has been assigned the treacherous task of neutralizing these anti-aircraft guns. However, any deviation from the plan could result in a suicide mission for the brave individuals involved.
