February 1943. Paddy Mayne and four comrades from the British special unit SAS parachute into the Ruhr area. Their objective: to attach a transmitter to Villa Hügel, the residence of the Krupp family, where, according to secret information, Hitler is expected to arrive personally. Disguised in German uniforms, they find themselves in the land of their enemy, embarking on a life-threatening mission. The target seems unattainable, as the villa is currently the most heavily guarded place in the German Reich.
