In the heart of Italy, a young police detective who is highly sensitive to art finds herself overwhelmed when exposed to famous paintings, experiencing the acute and disturbing phenomenon known as Stendhal Syndrome. This rare condition causes her to suffer vivid hallucinations and fainting spells when in the presence of exquisite artwork. During her investigation of a series of brutal rapes and murders in Florence, she becomes deeply affected by the syndrome, which blurs her grip on reality just as she is on the trail of the perpetrator. Her vulnerability becomes a significant handicap, putting her at both a professional and personal disadvantage in her pursuit of the criminal.

The detective's situation takes a drastic turn when she encounters the suspect in a famous museum, leading to a traumatic event that profoundly impacts her mental state and the investigation. As she delves deeper into the case, the lines between her hallucinations and reality become increasingly blurred, causing her to question her perceptions and sanity. This psychological battle not only complicates her mission to stop the murderer but also forces her to confront her own fears and trauma. The fusion of her psychological struggle with the criminal investigation creates a compelling narrative of obsession, art, and madness, setting the stage for a confrontation that tests the limits of her resolve and understanding of the human psyche.
