The synopsis for the movie reads, “When Father Novak and Sister Lu board a train from Montreal to New York City, they weren’t prepared for the danger and evil that would pursue them. After the train is taken over by the demon Asmodeus, Father Novak and Sister Lu must battle possessed passengers on a runaway train with Sister Lu forced to overcome her faltering faith and perform the first exorcism done by a nun.”

Keeyes recently directed 2024’s The Clean Up Crew, which stars Jonathan Rhys Meyers, Antonio Banderas, and more. Some of the other films he’s helmed in the past include 2017’s The Harrowing, 2021’s Rogue Hostage, 2021’s The Survivalist, 2022’s Code Name Banshee, 2024’s Cult Killer, and more, while he was also a producer on the 2025 action flick Guns Up with Kevin James, Christina Ricci, and Luis Guzmán.

In addition to the Black Canary role, Cassidy is known for starring in shows like Supernatural and Gossip Girl; she’s also been in movies such as 2006’s Black Christmas, 2010’s A Nightmare on Elm Street, and other titles.
