When Elizabeth's husband, Luc, dies in a tragic accident, her once-perfect life shatters. Isolated in their sprawling French estate, she struggles to rebuild her world while haunted by his memory. Determined to reconnect with life, Elizabeth hosts a dinner party with a carefully curated guest list: Dr. Marc, the calm and kind stranger who offers her solace; Paul, whose cryptic remarks cut too close to the truth; and Claire and Chloé, her oldest friends hiding secrets of their own.

As the night unfolds, the lines between reality and illusion blur. Conversations about loss and moving on trigger Elizabeth's spiraling grief, and Marc's uncanny resemblance to Luc becomes impossible to ignore. When she begins hearing Luc's voice and seeing his face where it shouldn't be, Elizabeth must confront a chilling question: is she losing her mind-or is something more sinister at play?
