A chilling descent into paranoia and fractured reality, GRIMM’s horror film PAROUSIA follows a young woman, played by Macy Savage, who begins to suspect that her quiet suburban home is not the sanctuary it appears to be. As she grapples with the unsettling feeling of being watched, her daily routines become increasingly fraught with dread. The arrival of a mysterious stranger, portrayed by Brian Grierson, only deepens her sense of unease, while her friend, played by Emily Addington Barker, offers a fragile lifeline to sanity. Joined by Ava Jackson in a supporting role, the cast navigates a labyrinth of psychological terror where the line between internal fears and external threats blurs. This tightly wound, seventeen-minute experience builds a suffocating atmosphere of suspense, leaving the audience questioning what is real and what is a manifestation of a mind under siege.
