(Reviewed by Foo) - Dr. Dan Potter (Dwight Schultz) has just moved into town and has taken a job as the new therapist at the insane asylum. He is assigned to a group of the most psychotic and dangerous inmates in the asylum. When Dr. Potter meets his new patients, the patients draw the (incorrect) conclusion that he must have murdered their previous therapist.

A local power outage enables the escape of four inmates: Frank (Jack Palance), Preacher (Martin Landau), Fatty, and the Bleeder. Of course, the top priority on the inmates' mind is to seek out and kill Dr. Potter, and perhaps his family in the process.

The movie follows a very similar path to both "Night of the Living Dead" and "Escape from Precinct 13". The family gets trapped in the house, while having to fend off the crazies. There is a very good twist on this premise, however, but I will not ruin it for those who wish to view the movie.

Although the plot has been done a million times, what makes this film so good are the performances. I have read other reviews that classified both Landau and Palance as being too over-the-top. There is a good reason for this, people. They are fucking insane! For my money, Martin Landau gives one of the best performances ever captured in a horror movie. I could not imagine someone being any creepier than he is in this film.
