Katariina ja Munkkiniemen kreivi

The story begins in the year 1860. The young Count of Munkkiniemi, Mauritz Armborg, and Katariina, the daughter of a farmhand on the estate of the Count's family, are attracted to each other. However, the count's grandmother, Yvonne Armborg, objects to the romance and tries to obstruct it. Elias Jahnukainen, a fisherman, is himself in love with Katariina and wants to marry her, but she has rejected his marriage proposals to date. Count Mauritz dreams of making a career as a violinist and wants to study music abroad. To try to divert Katariina away from her grandson, Countess Yvonne offers to finance Katariina's dowry if she is willing to marry Elias. In addition, Countess Yvonne introduces the young count to Ingeborg Liliecrona. However, Mauritz is not attracted to Ingeborg.

Mauritz and Katariina plan to elope, and make their way to Copenhagen and Rome. The lovers meet at an inn, and spend the evening together. At dawn, Mauritz leaves Katariina an old family heirloom, a necklace. However, a servant to Yvonne informs her of the lovers' plans. The lovers are intercepted before they can travel together to Copenhagen. Katariina is escorted back, apart from Mauritz.

Unhappy at being separated from Mauritz, she tries to commit suicide by jumping off a cliff, but Elias saves her. She then accedes to a marriage with Elias. Separately, Mauritz has continued his journey to Copenhagen, where he is confined for several weeks because of a severe illness. Ingeborg travels to Copenhagen, meets Mauritz, and falsely tells him that Katariina will arrive in Rome in the company of Countess Yvonne. However, upon their arrival in Rome, Mauritz meets Countess Yvonne, who has traveled alone. She tells him that Katariina has married Elias, which leaves Mauritz distraught.

Katariina and Elias have moved into the lower-income Katajanokan district. She has given birth to a son, whom she names Mauritz. Even though the Count is the biological father, Elias promises to treat the son as his own.

Seven years pass. Mauritz and Ingeborg have married, but Mauritz is unhappy because he is still in love with Katariina. At the end of the 1860s, Finland is enduring famine, and plague. Katariina writes a letter of intent to gain admission for her son into a good school, but her application fails, because Elias is of too low a social station.

One day, young Mauritz disappears. Katariina finds him at the house of the governor's wife, Elisabeth Gerhard, whose own son has died. Elisabeth offers to take care of young Mauritz. Katariina objects, but changes her mind after the death of her husband Elias from the plague. Katariina leaves young Mauritz in the care of Elisabeth, and also leaves the necklace with him. Elisabeth and young Mauritz travel to Rome, where young Mauritz meets Count Mauritz. He sees the necklace with young Mauritz, and realises that he is Katariina's son, and thus his own son.

The marriage between Count Mauritz and Ingeborg finally collapses, as the Count has requested permission to travel to Finland with young Mauritz. Ingeborg agrees to a divorce. Count Mauritz and young Mauritz return to Munkkiniemi to a solemn welcome. Count Mauritz plans to apologise to Countess Yvonne, who in her turn has since repented of her scheme to keep Count Mauritz and Katariina apart. When Countess Yvonne meets young Mauritz, she immediately feels great affection for him. Upon seeing the necklace in his possession, she realises that the child is her kin. In the meantime, Katariina has also learned of her son's return to Finland.

One day, Count Mauritz is walking in a park where he and Katariina spent past days of their time together. He begins to sing the "Romance", a song that they both loved. Unbeknownst to him, Katariina is in the same park, and hears the song. The couple finally reunite, as Count Mauritz asks Katariina to come home with him, to "our home".
