Build a movie plot around this: What game do Oskar and Thomas play? Scavenger hunt
Nine-year-old Oskar Schell (Thomas Horn), who suffers from Asperger syndrome, is the son of German American Thomas Schell (Tom Hanks).[5] Thomas would often send Oskar on missions to do something involving one of his riddles. The last riddle he ever gives Oskar is proof that New York City once possessed a Sixth Borough. In a flashback, Thomas and Oskar play a scavenger hunt to find objects throughout New York City. The game requires communication with other people and is not easy for the socially awkward Oskar who is told "If things were easy to find, they wouldn't be worth finding".On September 11, 2001, Oskar and his classmates are sent home from school early while his mother Linda (Sandra Bullock) is at work. When Oskar gets home, he finds five messages from his father on the answering machine saying he is in the World Trade Center. When Thomas calls for the sixth time, although Oskar is present to answer this call, he is too scared to answer. The machine records a sixth message which stops when the building collapses.
