Sister Cecilia, played by Sydney Sweeney, is an American nun of devout faith. She embarks on a new journey in a remote convent in the picturesque Italian countryside. Cecilia’s warm welcome quickly devolves into a nightmare as it becomes clear her new home harbors a sinister secret and unspeakable horrors.

Michael Mohan read a text message “Interested in directing a horror film?” from Sweeney, a close collaborator and the driving force behind her production company Fifty-Fifty Films. “…plunged me into what would become the most electrifying project of my career.”

Mohan describes his directorial intention: “And the story’s culmination, which I will only hint at here, is intended to leave audiences breathless, inviting introspection without prescribing answers—all unfolding within a tight 89 minutes.”

Collaborating on this film wasn’t just the greatest honor of my life; it was a chance to make something that could stand the test of time. My hope is that Immaculate feels like the ultimate rollercoaster ride, leaving you haunted, introspective, and beautifully traumatized,” concludes Mohan.

The supporting cast includes Álvaro Morte, Simona Tabasco, and Benedetta Porcaroli.
