context: A family is dislocated when small failings become extravagant lies. The film opens as a wealthy businessman, Servet, running a campaign for the upcoming election, is driving in his car alone and sleepy, struggling to keep his eyes open. Seconds later he hits and kills a pedestrian in the middle of the road. Servet panics when another car with a couple inside approaches. He sneaks away.
  EyÃ¼p, a man living in a slum at the Yedikule neighborhood in Ä°stanbul, with his wife and only son, is the driver of Servet. He wakes up in the middle of the night with his cell phone ringing. It's his boss, telling EyÃ¼p to meet him immediately. Shivering in shock, Servet explains the current events to his driver. His excuse is if the fatal accident comes out in press it would terminate his political career, so he proposes EyÃ¼p to take over the penalty and stay in prison for a brief period of time in exchange for a lump sum payment upon his release, whilst still paying his salary to his family so they can get by. EyÃ¼p accepts the deal.
  An unspecified time passes, summer arrives, and EyÃ¼p's son Ä°smail fails to enter college again. His mother, Hacer, who works in the catering division of a factory, starts worrying about her son after unpleasant events, and tries to convince him to get a job. Ä°smail suggests driving children between home and school but of course they don't have any financial source for this kind of an enterprise. Ä°smail asks his mother to request an advance payment from Servet without consulting EyÃ¼p. Hacer meets with Servet, in his office after the election (which he lost), and requests the money. After Hacer leaves the office and starts waiting for a bus at the stop Servet persuades Hacer to accept a lift from him back to her home.
  More unspecified time passes, and Ä°smail intends to visit his father. Things take a poor turn when he finds his mother having an affair with Servet. Ä°smail stands passive. After serving nine months in prison, EyÃ¼p is released. He senses things are "a little peculiar" inside his home. Hacer is in love with Servet and insists on maintaining their affair. Servet disagrees. That night, Hacer and EyÃ¼p are invited to the police station and informed that Servet has been murdered. Police officers interrogate the two and EyÃ¼p finds out that Hacer was cheating on him. He denies knowing anything about it. Ä°smail confesses to his mother that he murdered Servet. EyÃ¼p calms down when he pays a visit to a mosque. Afterwards, EyÃ¼p goes on to speak with a very poor man who works and sleeps inside a tea house in the neighborhood. EyÃ¼p makes the same proposition to the poor man, Bayram, that Servet made to him: to claim the crime committed by his son.
