Wroclaw 1997. Marianna extracts a metal cassette exposed by the flood from the basement and makes an incredible discovery. Inside is the Tagebuch - Lisa Weber's diary. Difficult to read the German manuscript, Marianna learns about the world of the previous tenants of the House under the Two Eagles. After World War I, little Lisa, her brother Karl and despotic father Johannes leave the bankrupt Koningsdorf estate for Breslau to start a new life. Johannes Weber renews his business with his friend, the enterprising Jew Goldstein, to quickly get back on his economic feet. When the children grow up, Karl decides to study architecture, and Lisa secretly dreams of medicine. The money earned by Johannes allows him to start building a new seat of the Weber family, the House of the Two Eagles. However, the vision of the house being built becomes a battlefield of generational ambitions between Karl and his father. Soon Johannes dies, leaving the growing children to fend for themselves. Fortunately, they are looked after by Goldstein.
