The Great Sacrifice (1944)
Albrecht Froben, though married to Octavia, falls in love with his neighbor, Äls Flodéen. She, however, is slowly dying from a debilitating disease. During an epidemic, Albrecht goes to bring her daughter to safety but he catches typhoid and and is quarantined in hospital. Octavia, realising the love match, and hearing that Als is now bedridden and dying, dresses up as him and rides by her gates every day to keep her spirits up - her bed is next to the window. Albrecht returns. Äls has a dream in which she talks to her projection of Albrecht and concludes that she does not wish to take part in this union and accepts death. Albrecht is reconciled with his wife.
