Durchs Brandenburger Tor. Solang noch Untern Linden...

In the year 1914: The assistants of cobbler Lehmann compete for the affections of his daughter Frieda. Actually she's in love with her ambitious cousin Fritz, but the cunning Franz knows how to string her along. When Fritz gets drafted, Frieda gives in and marries Franz. Soon Fritz is declared missing and the old cobbler dies of grief. Along the way Franz, who dodged the military service, earns his money with large-scale racketeering.
