The book is narrated through the eyes of Pat Peoples, a former history teacher that has moved back to his childhood home in Collingswood, New Jersey, after spending time in a Baltimore neurology hospital. Pat believes he has only been away a few months, soon realizes it has been years, and struggles to piece together his lost memories. He has a theory that life is a film created by God and that its "silver lining" will be his successful reunion with his wife Nikki. Pat embarks on a plan of self-improvement that includes regular jogging and fitness exercises and reading the works of American literature that his wife teaches her students. He grows upset after reading the tragic works of future suicides Ernest Hemingway and Sylvia Plath not understanding why the stories do not have happy endings. At a dinner with his friend Ronnie and his wife Veronica, Pat is introduced to Tiffany, who also has moved back home after losing her job after her husband's death.

As a condition of his release Pat makes regular visits to a therapist named Cliff Patel with whom he shares an enthusiasm for the Philadelphia Eagles. Pat is haunted by the music of saxophonist Kenny G. Dr. Patel deliberately triggers an outburst by playing "Songbird" a tune Pat associates with the event that had separated him from his wife, though he cannot remember the details of the event.
Pat and Tiffany become friends, they jog together regularly but they say little to each other. She mentions that she is "scouting" him for something. Much later, she explains that she wants him to be her dance partner, in return for which she will act as a go-between between him and Nikki, circumventing a restraining order Nikki has taken out on him. Tiffany requires Pat to give up The Eagles until the competition is completed. His family and friends are annoyed and confused by his unexplained refusal to attend games, and as the team has a run of bad luck partially blame him.

Pat trains with Tiffany and performs in the dance contest. To his surprise his friends and family attend the contest to support him. After the contest, Tiffany gives him several letters, supposedly written by Nikki. Pat wants to reunite with Nikki but Nikki demurs. Pat suggests a meeting, despite no reply, he slips away from his family on Christmas Day to meet Nikki. Nikki is not there, Tiffany is there and admits she has forged Nikki's letters and that she had been trying to help Pat move on and gain closure on his marriage because she, Tiffany, is in love with Pat. Pat is furious that the last two months of correspondence were a lie. In shock Pat runs and runs into an unfamiliar neighborhood and is mugged. By chance he encounters Danny his roommate from the Baltimore mental health facility and he helps Pat get to hospital and reunite him with his family. Pat still doesn't recall how he was separated from his wife, only when he watches his wedding video do the memories eventually return. After several weeks Pat recovers from his injuries and after receiving a letter agrees to meet Tiffany. She explains that Ronnie and Jake had forbidden her from attending his birthday. They talk and Pat explains that he went to see Nikki. Pat asked his brother Jake to drive him to see Nikki, and observed her from afar he realizes she has a new family and is happy, and accepts it as the ending of the movie of his life. Tiffany gives Pat a belated birthday present, a cloud chart and they lie on the ground and watch the clouds together. Tiffany pulls close to Pat and tells him she needs him. As they there on a frozen soccer field in the middle of a snowstorm Pat kisses her on the forehead and says "I think I need you too."
