context: Wayne Hayes (Robert Redford), and his wife Eileen (Helen Mirren) are living the American dream in a wealthy Pittsburgh suburb, having raised two children (Alessandro Nivola, Melissa Sagemiller) and built up a successful business from scratch. He is looking forward to a peaceful retirement with Eileen. Everything changes when Wayne is kidnapped in broad daylight by a former employee, Arnold Mack (Willem Dafoe). While Wayne tries negotiating with the kidnapper, Eileen works with the FBI to try to secure her husband's release. During the investigation, Eileen learns that Wayne has continued an extramarital affair that he promised to end months previously.
  Eileen is eventually instructed to deliver the ransom to the kidnapper, but Arnold takes the money without returning her husband; Arnold murdered Wayne the day of the kidnapping. Although Eileen's ordeal takes place over the course of a week, the film is edited to show Wayne's kidnapping as if it was happening at the same time.
  Arnold is eventually caught when he begins to spend the ransom money in the neighborhood where he lives. At a local grocery store, he uses a $100 bill to make a purchase. The store manager calls authorities and verifies the serial number on the $100 bill is on a watch list the FBI distributed to local businesses. During questioning Arnold is asked if he wanted to be caught, and he admits that the kidnapping was to get money for his depressed wife, but it took him all day to bring himself to kill Wayne and he couldn't live with the guilt of his crime. In the end, Eileen receives a loving note written by Wayne before his death.
