Plot
Arvid Stjärnblom, an aspiring journalist from Värmland, working as a proofreader for a daily newspaper in Stockholm, falls head over heels in love with Lydia Stille, a painter's daughter. With his low income, he doesn't think he could provide Lydia with an appropriate lifestyle. Rather than waiting for him, she chooses to marry the wealthy but much older landowner Markus Roslin. Years later, Arvid is married as well, and both couples have a daughter. When Arvid and Lydia see each other again, neither can overcome their mutual attraction. They begin a passionate affair, which greatly afflicts their loved ones, leading to dramatic events.
