ights and Days is a family saga of Barbara Ostrzenska-Niechcic, (played by Jadwiga Baranska) and Bogumil Niechcic, (played by Jerzy Binczycki) 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 Dabrowska 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. The cinematographic version is a condensation of the 12 part award winning TV serial of the same title and using the same cast and producers.
