It's the unsolved crime from over half a century that haunts an abandoned correctional facility for boys. In 1950 one of the juvenile inmates was beaten to death and buried in California's most notorious of detention centres. This means nothing to Liz, a college student who returns home on a college break to recover from a recent break up and mope about the house. It's when Ashley and her ex-boyfriend Danny extricate Liz from her self-imposed isolation that the three head out for the evening and end up on the grounds of the haunted Preston Castle where they explore the decaying depths of the once feared institution unaware that in the dark their worst fears will materialise.
