The film is based on a true dramatic story of the fate of a wonderful Russian woman - Countess Yulia Petrovna Vrevskaya, one of the first Petersburg beauties. The events of the movie take place during the Russian-Turkish war for the liberation of the Bulgarian people from the Turkish yoke. An early widowed baroness, having left Petersburg, and having invested all her money in organizing a volunteer sanitary detachment, she becomes a sister of mercy on the front of the Bulgarian war with the Ottoman Empire of 1878.
In the House of Marriages, the young couples are paraded one after other. The newlyweds sign the register, kiss and receive congratulations. The picture fades out and another house takes shape: house of executions. An antifascist resister condemned to die marries his beloved minutes before facing the firing squad.
