• Mystery
• Thriller
• Horror

A claustrophobic psychological thriller set within the oppressive atmosphere of a secluded boys’ boarding school, *Diabolique* centers on a chilling conspiracy born from shared desperation. A wife and her husband’s mistress forge an uneasy alliance to eliminate a domineering and cruel headmaster, meticulously planning and enacting his murder—only to be unravelled by the baffling disappearance of his body. The ensuing investigation isn’t a procedural hunt, but a descent into mounting paranoia and psychological unraveling for the two women, their guilt and fear amplified by the unsettling ambiguity of the situation and a casually observant investigator. The film trades in escalating tension and a stifling sense of dread, focusing less on the mechanics of the crime and more on the corrosive impact of secrets and the fragility of composure when faced with the impossible.
