The Unknown Girl

RELEASE DATE: September 8
DIRECTORS: Jean-Pierre Dardenne, Luc Dardenne
CAST: Adèle Haenel, Olivier Bonnaud, Jérémie Renier

Late one night, as a young doctor (the wonderful Haenel) and her assistant are closing up shop, a frantic young woman buzzes their buzzer. They’re long after hours, so they don’t let her in – but when the woman turns up dead nearby, the doctor feels a sense of responsibility, and an obligation to at least find out who she was, and how she got there. What first seems an innocuous and even honorable inquiry uncovers something far more sinister, but our investigator isn’t Miss Marple, or even Quincy M.D.; she’s the haunted, tenacious protagonist of a movie by the Dardennes (Two Days, One Night), which means The Unknown Girl rises far above its mystery thriller logline, fusing its genre framework with the thematic preoccupations of these extraordinary filmmakers. The result is unexpectedly effective, a tense whodunit with real stakes.
