[EX Q]: On Christmas Eve in 19th-century London, Fred is sliding on ice on a sidewalk. He meets Peter and Tim Cratchit, sons of his uncle Ebenezer's clerk, Bob Cratchit. When Fred reveals who he is, the boys take off in terror. Fred soon arrives at the counting-house of his miserly maternal uncle, Ebenezer Scrooge. After declining an invitation from his nephew to dine with him on Christmas, Scrooge rejects two gentlemen collecting money for charity. That night, Scrooge reluctantly allows his employee Bob Cratchit to have Christmas off with pay but orders him back all the earlier the day after. Later Bob accidentally knocks off Scrooge's hat with a snowball. Scrooge dismisses Bob and withholds a week's pay to compensate for his ruined hat, also demanding a shilling to make up the difference. Bob spends the last of his wages on food for his family's Christmas dinner.  In his house, Scrooge is confronted by the ghost of his deceased business partner, Jacob Marley, who warns Scrooge to repent his wicked ways or he will be condemned in the afterlife as Marley was. He tells Scrooge he will be haunted by three spirits. At one o'clock, Scrooge is visited by the youthful Ghost of Christmas Past, who takes him back in time to his early life. Scrooge is shown his unhappiness when he was left to spend the holidays alone at school, and his joy when his sister, Fran, came to take him home for Christmas. The spirit reminds Scrooge that Fran, dead for some years, is the mother of his nephew. Scrooge is shown his early career in business and money lending as an employee under Fezziwig.

[EX Q]: In Berkeley, California in 1988, Mark O'Brien is a poet who is forced to live in an iron lung due to complications from polio. Due to his condition, he has never had sex. After unsuccessfully proposing to his caretaker Amanda, and sensing he may be near death, he decides he wants to lose his virginity. After consulting his priest, Father Brendan, he gets in touch with Cheryl Cohen-Greene, a professional sex surrogate. She tells him they will have no more than six sessions together. They begin their sessions, but soon it is clear that they are developing romantic feelings for each other. Cheryl's husband, who loves her deeply, fights to suppress his jealousy, at first withholding a love poem that Mark has sent by mail to Cheryl, which she eventually finds. After several attempts, Mark and Cheryl are able to have mutually satisfying sex, but decide to cut the sessions short on account of their burgeoning feelings. One day sometime later, the power goes out in the building in which Mark lives, causing the iron lung to stop functioning and making it necessary for Mark to be rushed to the hospital. However, he survives and meets Susan Fernbach, a young woman with whom the audience senses he will finally find happiness. The film then cuts to Mark's funeral, held sometime later, and attended by four of the women he came to know and care for, including Cheryl. Father Brendan gives the homily and Susan reads the poem he had previously sent Cheryl.
