When Margaret and her husband Hal bought the large Victorian house on Hawthorn Street—for sale at a surprisingly reasonable price—they couldn’t believe they finally had a home of their own. Then they discovered the hauntings. Every September, the walls drip blood. The ghosts of former inhabitants appear, and all of them are terrified of something that lurks in the basement. Most people would flee. Margaret is not most people. Margaret is staying.

Episode Thirteen takes them to every ghost hunter's holy grail: the Paranormal Research Foundation. This brooding, derelict mansion holds secrets and clues about bizarre experiments that took place there in the 1970s.

But as the house begins to reveal itself to them, proof of an afterlife might not be everything Matt dreamed of.

Bertram Stone is a former Texas Ranger running from the changes of an ever-evolving world. Horses were being replaced by cars. Laws were changing how Bertram could deliver justice.

In a small town where the law rarely needs enforcing, everything is going according to his plan—until a great evil plunges Hamilton into horror.

Something lurks in the darkness of the trees. A group of friends goes on a hike in search of an ancient spring deep inside the forest.

She is malnourished, dehydrated, and hurt, but she keeps raving about the danger in the woods, repeating one incoherent word over and over in a foreign language.

It’s the mid-'90s. Grunge and flannel are fading as the Spice Girls and Hot Topic conquer the malls. Cherry gloss glistens on the lips of the youth. Modems hiss as America comes online.
