Nights and Days is a family saga of Barbara Ostrzeńska-Niechcic, and Bogumił Niechcic, against the backdrop of the January Uprising of 1863 and World War I. The film is a rather straightforward and faithful adaptation of a novel by Maria Dąbrowska with the same title. The plot is woven around the changing fortunes of a noble (upper-class) Niechcic family in the pre-WWI Poland. There are two main crossing threads: a social history one and an existential one.
