The year is 1980. Paranormal investigators Mick Sutherland and Archie Charlesworth have built their careers on confronting the unexplained across Northern Europe. But when a desperate summons draws them to the isolated home of Elizabeth Blair, they find themselves confronted with a presence unlike anything they've seen before. What starts as another routine case file rapidly grows more sinister. Across seven days, this presence begins to claw at their sanity, twisting their perception of reality itself. This entity isn't just threatening their lives; it seeks to shatter their bond and dismantle everything they believe. As the veil between life and death thins around them, Mick and Archie realize this is no ordinary haunting. This is Case 13.
