Answer the following question: Generate a question about the following movie plot: While collecting butterflies out in the English countryside, a young man named Freddie Clegg (Terence Stamp) stumbles across an old secluded house for sale. Looking through the house on his own, he seems most interested in the basement. He decides to buy the house, its purchase the catalyst for actually carrying out the plan he has devised for her. He wasn't sure if he could carry it out before coming across the house.The "her" in question is a young woman named Miranda Grey (Samantha Eggar), she a student at the Blake School of Art in London. Freddie knows her whereabouts at all times. On the day he decides to carry out his plan, he follows her from school to a pub where she meets with a young man. After that meeting which she seems sad about, she wanders around a secluded urban park. His van is parked so that she would have to get right next to it to pass. As she does, he jumps out of the van, grabs her, knocks her out with chloroform, and gets her into the back of the van. He drives her to his newly purchased house, and carries her still unconscious into the basement. He lays her down onto a bed, and walks out of the basement, bolting the door behind him. The basement door is behind a hidden door masked as a bookcase to the main part of the house. He goes into the kitchen to splash water on his face, when it starts to rain outside. Transfixed, he goes outside to lie in the rain. There, he reminisces about one of many painful encounters he had at the bank where he worked in Reading. He is being tormented by his colleagues, who call him the butterfly boy. His Aunt Annie (Mona Washbourne) visits him at the bank, something she is not supposed to do, telling him that he has won 71,000 in the football pools.Miranda eventually awakens, frightened not knowing where she is. She yells for help while pounding at the door, to no avail. She goes to the sink to splash water on her face. She notices that the makeshift bathroom area (there is no tub or shower) is designed for a woman, with many new women's toiletries...
