Task: Question Answering
Input (English): In early 19th century Styria, a beautiful blonde (Kirsten Lindholm) in a diaphanous gown materializes from a misty graveyard. Encountering the Baron Hartog (Douglas Wilmer), a vampire hunter out to avenge the death of his sister, the girl is identified as a vampire and decapitated. Many years later, a dark-haired lady leaves her daughter Marcilla (Ingrid Pitt) in the care of General von Spielsdorf (Peter Cushing) and his family in Styria. Marcilla quickly befriends the General's niece, Laura (Pippa Steel). Laura subsequently suffers nightmares that she is being attacked, and dies of a gradual sickness; whereupon Marcilla departs.Faking a carriage break-down, Marcilla's mother leaves her (now using the alias 'Carmilla') at the residence of a Mr. Morton, where Carmilla befriends and seduces Morton's daughter Emma (Madeline Smith). Thereafter Emma suffers nightmares of penetration over the heart, and her breast shows tiny wounds. Emma's governess, Madame Perrodot (Kate O'Mara), becomes Carmilla's accomplice. The butler and a doctor suspect them; but Carmilla kills each one. A mysterious man in black watches events from a distance, smiling (his presence is never explained). Having killed the butler, Carmilla takes Emma prisoner and departs. When Madame Perrodot begs Carmilla to take her too, Carmilla kills her. Emma is rescued by a young man named Carl (Jon Finch), and Carmilla flees to her ancestral castle, now a ruin. All this coincides with the arrival of the General, who brings a now-aged Baron Hartog. They find Carmilla's grave, which reveals that her true name is Mircalla Karnstien, where the General forces a stake into Carmilla's heart, and cuts off her head. Thereupon Carmilla's portrait on the wall shows a fanged skeleton instead of a beautiful young woman., Question: Who does Carmilla take prisoner?
Output (English): Answer: Emma
