In the spring of 2008, in New York City, while America is moving to the rhythm of the presidential elections, Marcus Goldman, a young and successful writer, is going through his own Calvary: he is unable to write the new novel that he must deliver to his publisher in a few months.

His deadline is approaching, when suddenly everything takes a different turn for him: his friend and former university professor, Harry Quebert, one of the most prominent writers in the country, sees his past come to the surface and is accused of murdering Nola Kellergan, a fifteen-year-old girl with whom he is said to have had a relationship, in 1975.
