Arclight Films is launching international sales on the horror-thriller “The Devil to Pay,” starring Danielle Deadwyler, Catherine Dyer and Jayson Warner Smith.

Arclight chairman Gary Hamilton made the announcement Monday, coinciding with the launch of the online American Film Market.

The story centers on a struggling farmer in an isolated Appalachian community, who fights to save her son when the cold-hearted matriarch of the oldest family on the mountain demands payment of a debt that could destroy a decades-old truce. Lane Skye and Ruckus Skye wrote and directed the film, and produced alongside Deadwyler, Martin L. Kelley, Allison Maier and Gabriel Olson.

“Danielle is a formidable talent, leading this gripping tale of familial defense through its pulse-racing twists and turns, as excellently plotted by Lane and Ruckus,” said Hamilton. “Our buyers have shown a consistent appetite for this kind of cerebral, elevated horror-thriller that both entertains and enlightens. We could not be more proud to add this special film to our AFM slate.”

Production companies on “The Devil to Pay” are Crooked Crow Films and Buckhead Film Group. “The Devil to Pay” was released in the U.S. through UnCork’d Entertainment and Dark Star Pictures on Oct. 6.

“This film was a true labor of love for us and we are so excited to partner with Arclight Films to help share this twisted Southern Gothic tale with the world at large,” said Lane Skye.

Deadwyler’s credits include HBO’s “Watchmen” and FX’s “Atlanta.” Dyer has starred on Netflix’s “Stranger Things.” Smith has starred on AMC’s “The Walking Dead.”
