The film follows Travis Peagler, the youngest of seven from Dayton, Oh, who has battled unseen forces for decades—witnessing their cruel torment of his former Marine father and troubled older sister while confronting his own life-threatening battle with an elite demonic entity. Fully awake, fully aware, Travis experienced a physical and psychological confrontation unlike anything publicly documented, forcing him to fight for survival against an overwhelming darkness.

​

Alongside Travis’s battle, his siblings have also faced chilling experiences, including the possession of his older sister, Kela. As the family unravels decades of trauma and unexplained phenomena, Satan Get Thee Behind Me challenges audiences to confront the unsettling reality of spiritual warfare.
