Three strangers with unusual psychic abilities are hired to investigate a series of chilling events at a haunted boarding school.

Harrow is haunted, they say. The mansion is a place of tragedy and nightmares, evil and insanity. First it was a madman's fortress; then it became a school.

Now it lies empty.

But an obsessed woman and a ghost hunter want to bring the house back to life to find out what lurks within Harrow. Together they assemble the people who they believe can pierce the mansion's shadows.
