A killer is after some people in a building while the power is out. That's it. Nothing much else happens. David Carradine's character is obnoxious. The other actors do their best, but everybody has to act like the killer is some invincible threat, and act really dumb. And they do their best to stretch this out to 90 minutes, but the script is very thin. Might have worked as a TV episode? But it's a pretty weak movie.
