When crime novelist Hector Lassiter hears his old friend Hemingway's missing manuscripts have turned up, he visits Hemingway's widow Mary to make sure the manuscripts don't reveal too many of Lassiter's personal details or hint too strongly at his writing methods. Meanwhile, professor Richard Paulson is determined to prove Mary killed her husband despite the commonly held belief that the great author committed suicide. As the two men endeavor to find answers to the mysteries surrounding Hemingway, it becomes evident the FBI was somehow involved.
