In a city where science and superstition intersect, a shadowy breach at a prestigious medical institute rattles the fragile equilibrium between discovery and danger. The atmosphere hums with a perpetual undercurrent of whispered rumors, sleek laboratory corridors, and the unsettling feeling that the very building itself might be holding its breath for something unspeakable. The tone is a blend of gritty journalism and cerebral noir, where every clue feels like a piece of a larger, almost mythic puzzle.

Carlo Giordani is a tenacious reporter whose curiosity is matched only by his willingness to chase stories into the darkest corners of the city. He soon finds an unlikely ally in Franco “Cookie” Arnò, a former star journalist now blind, whose extraordinary cryptologic mind perceives patterns that others miss. By his side is his sharp‑witted niece Lori, whose loyalty and intuition become vital in navigating the labyrinthine intrigue. Among the peripheral figures is Bianca Merusi, a confidante whose connections to the institute hint at deeper layers of secrecy.

Together, they are drawn into a complex mystery that intertwines a series of chilling crimes with the unsettling notion of genetic anomalies—specifically the controversial research into a rare chromosomal condition. The case feels like a twisted “cat o’ nine tails,” each lead a strand that could either unravel the truth or ensnare them further. The investigative journey promises a cerebral cat‑and‑mouse game, where intellect battles instinct, and every revelation carries the weight of ethical ambiguity.

The film’s mood oscillates between the stark fluorescent glow of laboratory halls and the muted shadows of rain‑slicked streets, underscoring a narrative that is as much about the internal darkness each character confronts as it is about the external enigma they pursue. As Carlo and Franco stitch together fragments of evidence, the audience is left with a persistent sense of curiosity—wondering how far the pursuit of knowledge can go before it becomes a weapon, and whether the truth can ever truly be uncovered without cost.
