Isn't Life Wonderful

A Polish professor and his family have become refugees in the aftermath of World War I. They try to survive in Germany during the period of the Great Inflation. Carol Dempster is Inga, a Polish war orphan who struggles to provide for the family that has taken her in, while accumulating a meager dowry from the rubble of depression-stricken Berlin so that she can marry Paul. Returning to his family, weakened by the battlefront's poisonous gases, Paul invests in his and Inga's future by tending a secret garden which he hopes will provide the resources for them to live, and which serves as a symbol of optimism for the two young lovers.
