During the mid 1920s, a network of spies collaborated with international business interests in order to rearm Germany, gearing her up for another World War. The Weimar Republic hid this secret weapons program under dummy companies all over Europe, including a renowned Film Production Studio. Three characters took the lead in this epic adventure full of glamour and the frantic energy of the roaring twenties: Spanish tycoon Horacio Echevarrieta (a local Citizen Kane), the most mysterious of all spies, Wilhelm Canaris; and a German Navy officer fascinated by risky business, Captain Walther Lohmann. Together, they built the best submarine in the World, and dreamt of an empire of high-tech military industry, until they were hit by the financial storm of 1929.
