A young newlywed woman begins to have disturbing nightmares just after settling into the old mansion that has belonged to her husband's family for centuries. When her sinister dreams come true, the innocent bride is caught in a maddening maze of unspeakable horrors.

As a thirteen year old, Martha Caldwell witnessed the death of her parents in a terrible railway accident. Barely surviving the tragedy herself, Martha was struck dumb due to the shock. Now an adult, the still mute Martha lives with her uncle Ralph in the Spanish countryside. Martha's cousing Jenny arrives to be with the family but is quickly stabbed to death. It appears that a sex maniac is roaming the countryside; killing pretty young girls. The already traumatized Martha seems likely to be the next victim but the case turns out to be far more complicated than it would first seem.
