The Voices of Our Mother has been acquired by Shudder, ahead of its North American premiere at Panic Fest in Kansas City.

The film follows Harriet Scaflen after the death of her mother at the age of 95. In the aftermath, Harriet has an unexplainable health scare, bringing her four estranged children to the family home to care for her.

As their past animosities and secrets are revealed, they soon realize their mother’s health issues may be supernatural, and the awoken evil inside her is seeking revenge on her children for her own survival.

It is written and directed by actor Mark O’Brien (Ready or Not, Arrival).

Sheila McCarthy (Anything for Jackson), Georgina Reilly (Pontypool), O’Brien, Carolina Bartczak (X-Men: Apocalypse), Alex Ozerov-Meyer (“Slasher”), Anna Ferguson (“Heartland”), and Shawn Doyle (“The Expanse”) star.

Christopher Giroux & Justin Rebelo of Vortex Productions (Anything for Jackson) produce. Executive producers include Jesse Ikeman, Nataline Rodrigues, and Bill Marks.

“Mark is a rare genre-blending talent who has proven his skill both in front of and behind the camera,” said Shudder’s Senior Vice President of Acquisitions and Productions, Emily Gotto. “His latest work on The Voices of Our Mother proves to be a haunting supernatural horror, and we’re thrilled to give this story a platform for Shudder’s viewers.”

Deadline first reported on the acquisition.
