Kathleen Evans is well now. She is free to leave the psychiatric institute in San Francisco anytime she wants. Still, the doctors want to ease her transition back to every day life so they decide to send her first to one of the most beautiful spots on earth, a placed called Vikingsholm on the shore of Lake Tahoe's Emerald Bay. Here is where she will acclimate herself to the outside world once again. But something is not right. Strange phone calls filled with static and a distant voice she almost can't hear begin to frighten her. And, if she is alone in her part of the mansion, what is the whispering she hears in the walls, the crying at night, the footsteps in the empty room a floor above? There is one thing, though, that bothers her more than all of that. If she is really cured, why can't she remember anything about her past?
