In the remote French Alps, veteran detective Pierre Niemans investigates a brutal murder at a prestigious university. The victim, horribly mutilated and hanged from a cliff, appears to be part of a larger, more sinister mystery involving the elite institution. As Niemans delves into the peculiar life of the university, he uncovers a rigid and secretive community that prides itself on excellence, yet seems haunted by dark secrets. Parallel to Niemans' investigation, in a nearby town, young and spirited detective Max Kerkerian looks into the desecration of a child's grave and a school burglary. While seemingly unrelated, these events reveal connections that suggest something far more extensive and ominous is afoot.

As both cases unfold, the detectives' paths intersect, uncovering clues that point toward ancient rituals, genetic experiments, and chilling secrets underlying the academia. Kerkerian's intuitive approach contrasts with Niemans' methodical style, yet their collaboration becomes essential as they confront a cloistered society resistant to their inquiries. The investigation intensifies as the detectives face growing dangers and chilling figures determined to shield their secrets at all costs. With mounting tension, they race against time to unravel a mystery threatening to unleash further violence. The chilling landscape mirrors the icy resolve of their adversaries, as the detectives push deeper into the heart of darkness and the hidden motives that have terrorized communities and sullied reputations.
