After several locals are viciously murdered, a Louisiana sheriff (David Janssen) starts to suspect he may be dealing with a werewolf.
Films like this one (as well as "Dark Night of the Scarecrow") prove that once upon a time, movies on television could actually be good. Today, that may be true, but in my opinion far less often. (The SyFy channel single-handedly lowers the bar on made-for-TV movies.)
This film introduced me to the term "loup-garou", a type of werewolf that is common in the culture of the Indian Ocean island nation of Mauritius. I do love how a plot point is that the townspeople do not know the term or even how to say it, with "loukarook" and other variations being used.
This also taught me about the fictional "Seibert's syndrome", an offshoot of blackwater fever. That fever releases hemoglobin directly into the blood vessels and into the urine, frequently leading to kidney failure. Pretty sure that the guy allegedly suffering from it in this movie does not know what he is talking about.
Sure, the werewolf (when we finally get a good glimpse) is a bit cheesy. But that is fine by me. Give me a well-crafted 1970s film over today's version of werewolves any day of the week. I would rather see a guy with a decent five o'clock shadow running amok than Taylor Lautner and his washboard abs sulking.
