Jess, a newly separated mother and nurse, moves into her old family farmhouse with Tyler, her teenage daughter, and Owen, her eight-year-old son. One night, the family dog senses something in the woods and runs off to find it. He returns a couple of days later and attacks Owen, savagely biting him before Jess is able to intervene. Owen is rushed to the hospital. His condition worsens, and no one can figure out why... until Jess discovers a disturbing cure...

Six people unwittingly find themselves locked in another series of escape rooms, slowly uncovering what they have in common to survive. Joining forces with two of the original survivors, they soon discover they've all played the game before.

In this crime horror thriller inspired by the style of 70s horror films from directors like Brian De Palma and Dario Argento, an introverted husband and father named Evan, who works as a high school guidance counselor, becomes a brutal vigilante serial killer who targets all those who abuse the children who confide in him, especially if the abusers are their parents.
