The story of the final months of author F. Scott Fitzgerald as told by Frances Kroll, the young woman who was his secretary at the time. In 1939, Frances, an aspiring writer, finds work as a secretary to F. Scott Fitzgerald after promising to keep secret a new novel he is beginning about the movie industry. Despite his literary genius, Fitzgerald is haunted by fantasies of his institutionalized wife Zelda, is burdened with a drinking problem, and is involved in a tumultuous relationship with his mistress Sheilah Graham. Frances is sensitive to his problems and becomes a trusted confidante. With the support of Frances, Fitzgerald is able to write what critics call potentially his best work -- "The Last Tycoon." Unfortunately, Fitzgerald dies before the novel is completed, but through Frances's efforts it is published in its incomplete form.
