The Phantom Baron

In 1826, the widowed Countess of Saint-Helie plans to move in with her elderly uncle, the aged Baron Carol. She arrives to the Baron's castle with her young daughters Elfy and Anne, but she learns that the Baron has disappeared and that he is reputed to have become a ghost. The Countess moves into the habitable part of the house anyway, deciding to wait for the Baron's return. A decade later, Elfy and Anne have become beautiful young women, but they have no dowry to attract prospective husbands. The countess attempts to arrange a marriage between Elfy and the young cavalry officer Alberic de Marignac, who is not interested in a dowry. Unknown to their mother, both Elfy and Anne are in love with their poor childhood friend Herve. On the eve of her engagement to Alberic, Elfy accidentally traps herself in a centuries-old dungeon of the castle. While searching for her sister, Anne privately discovers a secret room which contains Baron Carol's treasures, the Baron's mummified body, and legal documents indicating that Herve was the baron's secret son and intended heir. Elfy is rescued from the dungeon, but Anne maintains secrecy about her discoveries. She has a plan to marry Herve, though she is surprised when a sleepwalking Herve enters her bedroom with apparent romantic intentions.
