Serial killer (Lenny Von Dohlen) escapes during the inevitable thunderstorm to stalk Dr. Matt McCoy, whose treatments certainly haven't alleviated his murderous condition.
McCoy, of course, lives in an old dark house deep in the woods where the police can't be relied onto save the family. Joanne Pacula clutches her throat prettily as the imperiled wife, while George Lazenby looks gob-smacked as a supporting victim with an Australian bimbo girlfriend.
With more ranting dialogue than is advisable for suspense purposes and a ridiculous parade of cliches passed off as a plot. Endearingly old-fashioned.
