The Unseen (1980) Synopsis & Summary

In this taut horror outing, three female journalists head out for isolated Soveg, California to cover a popular Danish festival. Unfortunately, they can't find a motel and end up staying at a strange old mansion owned by a mysterious fellow who is far worse than he seems. He has not only committed patricide, he is also incestuously involved with his own sister who gave birth to their deformed son, whom he has chained in their basement. The three spend a terrifying night, and in the morning only one has survived. - Sandra Brennan, All Movie Guide
