In the high-stakes world of fine art authentication, a renowned expert finds her own reality beginning to fracture. Kate Winslet delivers a gripping performance as a brilliant but emotionally guarded art historian whose life is built upon discerning truth from forgery. When she is called to examine a potentially priceless painting with a mysterious provenance, the investigation pulls her into a labyrinth of deception that challenges her professional judgment and personal convictions. As the line between the authentic and the imitation blurs, she is forced to confront uncomfortable truths about the art world, the nature of value, and the stories we tell ourselves to survive. Directed and written by Scott Z. Burns, this tense drama masterfully builds an atmosphere of paranoia and moral ambiguity, exploring how the pursuit of a fake masterpiece can expose the most genuine human frailties.
