Home invasion movie stars Deborah Kara Unger, Johnathon Schaech, and Stephen Dorff

The home invasion horror-thriller Jackals concerns a family that will do anything to get their estranged son back from a murderous cult, only to find themselves under siege when the cultists surround their cabin. A vicious battle unfolds, testing familial loyalties, and unleashing a bloodbath in which there are few survivors.

Jackals stars Deborah Kara Unger (Crash, Silent Hill), Stephen Dorff (Blade, the upcoming Texas Chain Saw Massacre prequel Leatherface), Johnathon Schaech (That Thing You Do!), Ben Sullivan (Hell on Wheels), Chelsea Ricketts (Scream Queens), and Nick Roux (Jane By Design).

The film is directed by Kevin Greutert, whose previous credits include 2009’s Saw VI, 2010’s Saw: The Final Chapter, and 2014’s Jessabelle. The film is written by Jared Rivet and produced by Tommy Alastra.

Scream Factory Films is releasing Jackals in theaters and on demand, Sept. 1
