The film, shot on location with the support of the Beresford, South Dakota community providing authentic props and costumes, tells the story of Wava, a spinster carrying the torch for her best friend’s husband.   A tragedy causes a rupture in the friendship, leaving a void in both women’s lives and disrupts the social order of the small community. PRAIRIE SONATA is a lushly visual, quiet and poetic homage to the intrepid women who helped forge the American heartland.
