The monster hunter Geralt of Rivia travels to Toussaint, a picturesque duchy that has remained largely untouched by the war raging elsewhere. He accepts a contract from Duchess Anna Henrietta to track down a mysterious beast that has brutally killed several of the region's knights. As Geralt investigates the killings, he finds that the sunlit, wine-growing land hides darker secrets, and an old friend he believed dead resurfaces to complicate the hunt.
