Movie plot title: Marathon Movie plot: A young man with autism, named Cho-won, finds release only in running. As a child, Cho-won regularly threw tantrums, bit himself, and refused to communicate with othersfinding solace only in zebras and the Korean snack, choco pie. His mother never gave up on him and was determined to prove to the world that her child can be normal. As Cho-won gets older, he begins to find a passion for running and his mother is there to encourage and support him. Even though their family suffers from financial difficulties, they find a former marathon champion, Jung-wook now a lethargic older man with an alcohol problem. Jung-wook, who is serving community service hours as a physical education teacher for a DUI, grudgingly accepts the offer to train Cho-won in marathon running, but eventually becomes lazy with him. The coach often takes Cho-won's snack, and takes Cho-won to a jjimjilbang to relax. Even though Jung-wook slacks off most of the time, Cho-won's determination for running is firm (he accidentally runs 100 laps around a soccer field when the coach told him to without literally meaning it). He takes third place in a 10km running race, which causes his mother to set another goal for her son: to run a full marathon under three hours. This is not an easy task, however, as Cho-won wants to win but doesn't know how to pace himself. Therefore, his mother pleads the coach to run with Cho-won in order to teach him how to pace his running. The movie shows the emotional struggles of a mother who is not sure if she is forcing her son to run or if it truly is his passion. The movie further explores and shows deep love and genuine purity through Cho-won.

A: full marathon

Question: Why must johnny and Fay check the luggage instead of carrying it on the plane? Movie plot title: The Killing Movie plot: Johnny Clay (Sterling Hayden) is a veteran criminal planning one last heist before settling down and marrying Fay (Coleen Gray). He plans to steal $2 million from the money-counting room of a racetrack during a featured race. He assembles a team consisting of a corrupt cop (Ted de Corsia), a betting window teller (Elisha Cook Jr.) to gain access to the backroom, a sharpshooter (Timothy Carey) to shoot the favorite horse during the race to distract the crowd, a wrestler (Kola Kwariani) to provide another distraction by provoking a fight at the track bar, and a track bartender (Joe Sawyer). George Peatty, the teller, tells his wife Sherry (Marie Windsor) about the impending robbery. Sherry is bitter at George for not delivering on the promises of wealth he once made her, so George hopes telling her about the robbery will placate and impress her. Sherry does not believe him at first but, after learning that the robbery is real, enlists her lover Val Cannon (Vince Edwards) to steal the money from George and his associates. The heist is successful, although the sharpshooter is shot and killed by the police. The conspirators gather at the apartment where they are to meet Johnny and divide the money. Before Johnny arrives, Val appears and holds them up. A shootout ensues and a badly wounded George is the sole survivor. He goes home and shoots Sherry before dying. Johnny, on his way to the apartment, sees George staggering in the street and knows that something is wrong. He buys the biggest suitcase he can find to put the money in (and struggles to lock it properly). At the airport Johnny and Fay aren't allowed to take the suitcase along as hand luggage because of its size, and instead must check it in as regular luggage. Johnny reluctantly complies. While waiting to board their plane they watch as the suitcase falls off a cart onto the runway, breaks open, and the loose banknotes are swept away by the backdraft from the plane's propellers. Fay and Johnny leave the airport but are unable to hail a cab before officers...
