Five years after surviving satanic serial killer Henry Decker (Woodward), Julia (Sothcott) is still haunted by the devastating horrors she endured. Plagued by PTSD and terrifying visions of her tormentor and living back with her mother (Ford), her whole life has been on hold, until now, with the maniacal murder dead maybe it’s time to move on... But pure evil never dies and hidden within the house where Decker's killing spree ended and Julia narrowly escaped with her life lies the Harbinger, a sinister fortune-telling machine that holds all the cards.

When paranormal TV presenter Mike Craggs (Webster) invites Julia on his show to recount her harrowing ordeal with Decker, he makes her a life-changing offer she just cannot refuse, but things are about to take a shocking turn. In the hope of finally confronting her past, Julia reluctantly joins the presenter, a team of ghost hunters, psychics, occult experts and television production crew, to record the show. But when they descend on the house of horrors, they accidentally stumble on the Harbinger, the malevolent machine that that predicts the grisly deaths awaiting each member of the group.

As the body count rises and escape becomes impossible, Julia discovers the horrifying truth, that Decker’s soul has been transferred into the machine... Trapped in limbo, the killer needs six souls to walk the earth again. Can Julia and the team stop him before the Harbinger claims them all?
