It is the turn of 19th and 20th century. An
impoverished young noblewoman, Ewa Pobratyńska (Grażyna Długołęcka),
falls in love with a lodger of her parents', Łukasz Niepołomski (Jerzy
Zelnik). An affair with a married and - as it turns out - faithless man
is the beginning of her moral fall. An unwanted pregnancy and
infanticide, a relationship with a con man, Pochroń (Roman Wilhelmi) and
prostitution make up for the main components in the story of the
heroine's sin, a story with no chance for a happy ending.
