The Psychotronic Film Society (the longest-running independent cinema organization in the area)continues its ongoing Wednesday night series of overlooked, underappreciated and otherwise marginalized feature films Nov. 8 with a rare public viewing of “Girl with Hyacinths” at The Sentient Bean.

Virtually unknown in the U.S., where it has never been officially released on home video in any format, this incredibly under-the-radar black-and-white Swedish mystery drama is considered one of the earliest and best examples of so-called “Scandi-Noir,” or the Scandinavian genre of crime dramas and suspense thrillers rooted in the initial wave of Hollywood film noir of the 1940s and early 1950s.

Shot in 1949 and released in Sweden in 1950, it also played theatrically in Finland in 1953, and was essentially forgotten until it was showcased in a retrospective at Taiwan’s Taipei Film Festival in 2012. Directed by Hasse Ekman, it’s the tale of a man who doggedly investigates the final hours of his late neighbor, a beautiful yet secretive young girl named Dagmar Brink who has mysteriously committed suicide.

Beautifully photographed and ably acted, this lost gem impresses most who view it. In fact, it led no less a filmic genius than iconic Swedish director Ingmar Bergman (“The Seventh Seal,” “Persona”) to declare this unpretentious motion picture “An absolute masterpiece… Perfect.”
