I am a movie director and I just received the following movie plot. Could you help me answer this question? If not, let me know by writing "Not answerable". Plot title: The Flight Before Christmas Movie plot: Niko, a young reindeer, was told by Oona, his mother, that his father is one of the "Flying Forces", Santa's flying sled reindeer. Niko dreams of joining his dad as a flying reindeer but he is unable to fly. While trying to fly with the encouragement of Julius, a flying squirrel who takes on the role of a mentor and father figure, the other young reindeer teased Niko. To avoid further teasing, Niko and his friend Saga leave their protected valley so Niko can practice without any disruptions. Niko gets spotted by two of the wolves, and escapes to his herd in panic, not thinking about the repercussions. While the herd is fleeing the valley, Niko overhears others talking of how his actions have damaged the herd. He decides to leave the herd in an attempt to find his father and Santa's Fell. When Niko is discovered missing, Julius chooses to look for Niko as he can search without leaving a trail as fresh snow is falling. Once he finds him, Julius cannot convince Niko to return to the herd and reluctantly joins him in the search for Santa's secret location. Meanwhile, Essie, a lost pet poodle, stumbles upon the wolf pack and is about to be eaten, but suggests to Black Wolf the idea of killing Santa's Flying Forces reindeer. Essie is considered Black Wolf's good luck charm for this idea and is spared, but is also forced to join the pack on this grim plan. Niko and Julius discover Wilma, a weasel, stuck in a small tree branch and rescue her. She is not pleased because she feels she has to save the lives of Niko and Julius before she can go on with her life. Julius and Niko get lost and separated in a sudden blizzard and Niko wakes under a pile of snow, unnoticed by the wolf pack that is nearby. Niko overhears Black Wolf resolving to kill Santa as well and take his place and bring death instead of presents to boys and girls. When Niko is discovered, he flees and finds Julius, but the two are cornered between rock cliffs. Wilma shows up in the overhanging snowdrifts above and sings a song that destabilizes the... My question: What is Niko's dream?
