Dr. Leo Bain (Donald Pleasence) is one of those wacky doctors who thinks the patients at a psychiatric ward shouldn’t be called crazy or locked up and heavily medicated. They need kindness and understanding. They should be more or less allowed to do what they want, and instead of correcting their delusions, you should just run with them. Except for the people on the third floor. Those guys are nuts. They have to be securely locked away.
Even then, they make the floor look rather cozy. Oh, there are big, strong doors that can swing shut and lock in an instant, and if anyone tries to open a window, barricades come down fast. But if everyone behaves, then the place looks like a nice place to live.
The film makes a big deal about the electric locks. Those doors open and shut electronically. The windows are the same. A guard says they are perfectly safe as long as the power doesn’t go out. So naturally, the power goes out.
The four guys on the third floor escape and wreak havoc. They will eventually find their way to Dr. Dan Potter’s (Dwight Schultz) house. He’s a new psychiatrist at the hospital, having just replaced a guy who moved to another town. But the third-floor guys think he must have killed that guy, and now they want revenge.
The back half of the film becomes a station-under-siege film. It’s pretty good.
It’s also pretty weird. The third-floor guys are played by Martin Landau (as a pyromaniac preacher), Jack Palance (and a disturbed former POW), Erland Van Lidth (as a child molester known as “fatty”), and a dude who only shows his face at the end and is only known as “Bleeder.”
Before they lay siege to Potter’s house, they go into town where everybody is looting because all that stands between society and chaos is a little power outage. They have some fun and get some weapons. It is a bit silly, really.
Our villains are having a lot of fun. Donald Pleasance isn’t really given enough to make his character interesting. Once the siege starts, things get interesting. I love a good base-under-siege story, and this one’s done well.
It is a film I’m happy to watch during Spooky season, but not one I’m likely to ever return to.
