With Fire and Sword (Ogniem i mieczem)

The 17th Century Polish-Ukrainian borderland is torn by a Cossack uprising. On his way back from Russia the young Polish Colonel Skrzetuski meets the beautiful Helena in a broken coach. He falls in love with her and in almost no time confesses his feelings to her to find out they are reciprocal. Unfortunately, as a result of her Aunt's plot, Helena had been promised to a Ukrainian soldier Bohun in return for his resignation from the right to family property. When Skrzetuski finds out about the plot, the Aunt agrees to give Helena to him. Bohun, who is also madly in love with Helena, goes mad and burns the property down, killing the Aunt's sons. Thanks to a companion of Skrzetuski, Helena can take refuge in the castle of Bar.
