“Alone,” the latest film from prolific horror director James Cullen Bressack, comes with one of the year’s creepiest premises: Alys, a sex trafficking victim who escaped from captivity ten years earlier, is lured into a terrifying survive-or-die scenario by someone from her past.

It’s a good fit for Spain’s annual Sitges film festival, which highlights fantasy and horror from around the world. “Alone” will have its world premiere in October as part of Sitges’ Midnight X-Treme lineup, and ahead of its public debut comes the extremely unsettling official trailer. Watch it exclusively at the top of the page now.

Starring Yulia Klass as Alys and Bruce Davison as the psycho who lures her to a mountain home in the middle of nowhere in the cold dead of winter, “Alone” also features Josh Kelly (“Transformers” franchise), Mark Rolston (“Saw,” “The Departed”), Michael Paré (“BloodRayne,”), and Michelle Burke Thomas (“The Final Wish”).

Written by Philip Daay and produced by Bressack and Micah E. Brandt of UFO Pictures with T. Patman-Thomas serving as executive producer, “Alone” screens for Sitges film festival attendees Oct. 5 at the Tramuntana Meliá, and Oct. 6 at Prado.

Bressack’s previous work includes “To Jennifer” (2013), “White Crack Bastard (2014),” “Pernicious” (2015), “Limelight” (2017) and the very enjoyable (trust us) Animal Planet sci-fi horror film “Blood Lake: Attack of the Killer Lampreys.”
