In a secluded mountain retreat near Grenoble, novelist Sandra Voyter finds herself amidst turmoil when she initially cancels an interview with a young student, disturbed by the loud music emanating from the attic, courtesy of her husband Samuel Maleski. After the student departs, Sandra's visually impaired son Daniel ventures outside with his loyal guide dog, Snoop. Their return takes a tragic turn when they discover Samuel lying motionless on the ground, seemingly the victim of an accidental fall.
As the investigation unfolds, Daniel's conflicting accounts about the circumstances surrounding his father's demise, coupled with the grim fact that Samuel had suffered a head injury prior to his fall, raise immediate suspicions. The emergence of an audio recording capturing a heated dispute between Sandra and Samuel exacerbates the situation, leading to Sandra's indictment on charges of homicide. This development prompts an intense scrutiny of their tumultuous relationship.
During the gripping trial, Sandra's defense asserts that Samuel fell from the attic window, receiving fatal injuries upon impact with the shed below. In stark contrast, the prosecution contends that Sandra was responsible for Samuel's death, suggesting she delivered a deadly blow and pushed him from their second-floor balcony. As the courtroom tension escalates, Sandra confronts her husband’s psychiatrist, questioning his shared responsibility for Daniel’s visual impairment, which originated from an accident under Samuel's watch.
The audio recording reveals a chilling glimpse into their volatile relationship, with Samuel hurling accusations of plagiarism, infidelity, and emotional manipulation at Sandra. These revelations illustrate that their problems went far beyond a single event; the prosecution boldly claims that the recorded violence stems solely from Sandra, while Sandra counters, asserting that her husband equally instigated the physical confrontation.
Adding to the tension, the prosecution introduces allegations regarding Sandra's extramarital affair from a year earlier, insinuating that Samuel's loud music was a reflection of his jealousy. They further argue that Sandra’s tendency to incorporate personal struggles into her writing draws unsettling parallels between the murder of her husband and the thoughts of a character in her latest novel.
Defiantly, Sandra argues that one audio recording does not encapsulate the true fabric of their relationship, nor do the musings of a fictional character mirror her own reality. As the trial surges toward its climax, Sandra's fate hangs delicately in the balance, leaving audiences to ponder the intricate boundary between reality and fiction.
As Daniel’s emotional turbulence reaches a critical point, he resolves to take the stand before the jury makes its verdict known. Aware of the potential for external influences, the judge imposes strict guidelines to assure the integrity of Daniel's testimony, appointing Marge Berger to oversee the proceedings. In a bold act, Daniel requests that Sandra vacate their home for the weekend, opting instead for solitude with Marge and Snoop, in an effort to process his profound emotions. His memories of Samuel's tragic overdose, compounded by Snoop's sickness—possibly triggered by consuming his vomit—serve as haunting reminders of the unrelenting despair that can accompany pain.
As Daniel confides deeply in Marge, she poignantly suggests that if he struggles to untangle the truth, he should instead focus on what resonates as truth for him personally. This profound realization paves the way for Daniel's moving appearance on the witness stand, where he openly shares his belief in his father’s potential suicide, ultimately rejecting the possibility of murder.
Daniel reminisces about a somber conversation with Samuel that occurred while they transported Snoop to the veterinarian. He recalls how his father's words appeared to foreshadow his own mortality, an implication that sheds new light on the tragic circumstances of his death. Ultimately, Sandra’s acquittal depends heavily on Daniel’s heartrending testimony.
As the emotional upheaval begins to settle, Daniel and Sandra share a tender reunion, revealing their fears and hopes. They embrace in a profound moment of understanding, confronting the weight of their shared loss. Later, as night falls, Sandra seeks solace in bed, her gaze lingering on a cherished photograph of herself with Samuel. Meanwhile, Snoop curls up beside her, symbolizing the indelible bonds that continue to exist even beyond death.
