input question: Generate a question that has the following answer: Nika for the following movie plot: The film starts with a brief recollection of the "Killing Angel", a dangerous assassin that has been operating in most of southeast Asia. The Killing Angel has no known accomplices or colleagues, is not affiliated with any government, religious, or criminal organization, and to this date their true identity has still remained secret. The Killing Angel is believed to be responsible for 6 murders in the past year alone, with only one thing connecting each of the assassinations - all the victims were criminals and deserved to die.Then the movie quickly moves on to the Killing Angel's most recent killing, the well-publicized assassination of a notorious ex-yakuza crime boss. Working swiftly, the Killing Angel is able to overcome the criminal's defense systems, quickly incapacitating the boss's bodyguards and isolating his target. In a fit of desperation, the crime boss promises to triple whatever fee the Killing Angel is being paid to kill him, then goes on to warn the vigilante that there is a massive revenge fund set to avenge his killing. Ignoring his pleas, the Killing Angel silently kills the crime boss.The scene then switches over to the story of Fu (Jet Li), a small-town gang member who lives an extremely simple and modest lifestyle, albeit being a contract killer.

input question: Generate a question that has the following answer: Elsa for the following movie plot: SS officer Ralf (David Thewlis) and his wife Elsa (Vera Farmiga) have a twelve-year-old daughter, Gretel (Amber Beattie), and an eight-year-old son, Bruno (Asa Butterfield). The well-to-do family must move to the "countryside" when the father is promoted (to Obersturmbannfuhrer). Unknown to Bruno, the new house is near a Nazi concentration camp, and Ralf is the new commandant. Bruno initially dislikes the new house as he always has to stay in the house or the garden; also there are no other children to play with, apart from his sister. From his bedroom window, Bruno spots a barbed wire fence with people in "striped pyjamas" behind it. Though he thinks it is a farm, it is the camp with Jewish people in their camp clothing. Bruno is forbidden to go there, because according to Ralf, "they're not really people"; it is agreed that at least they are a bit weird, as demonstrated by their clothing.Bruno goes there anyway, secretly, and becomes friends with a Jewish boy, named Shmuel (Jack Scanlon), whom he meets at the fence, and who is the same age. Shmuel tells Bruno that he is a Jew and that the Jewish people have been imprisoned here by soldiers, who also took their clothes and gave them the striped camp clothing, and that he is hungry. Bruno is confused and starts having doubts about his father being a good person. Later, he is relieved after seeing a propaganda film about the camp (that is a parody of Theresienstadt). Bruno often returns to the fence. He brings Shmuel food and plays draughts (checkers) with him through the fence.An elderly Jewish man named Pavel (David Hayman) is a servant in the family home; he is treated rudely by Ralf's adjutant, Obersturmfuhrer Kotler (Rupert Friend). Formerly a doctor, Pavel mends Bruno's cuts when he falls off his homemade tire swing.Ralf hires Herr Liszt (Jim Norton) to tutor Gretel and Bruno, although in reality he is brainwashing them with anti-Semitic Nazi propaganda.
