The synopsis for the film is as follows:
After a shooting at a police funeral, reclusive ex-cop Gannon finds himself unwittingly forced out of retirement when he realizes that the killer belongs to the same militia he joined after quitting the force. Understanding that the shooting could set off a chain reaction of copycat violence across the country, Gannon quarantines his fellow militiamen in the remote lumber mill they call their headquarters. There, he sets about a series of grueling interrogations, intent on ferreting out the killer and turning him over to the authorities to prevent further bloodshed.
The film is written and directed by Henry Dunham and stars James Badge Dale, Brian Geraghty, Patrick Fischler, Happy Anderson, Robert Aramayo, Gene Jones and Chris Mulkey.
The Standoff At Sparrow Creek is scheduled for cinematic release on the 18th January 2019.
