Like a 70s exploitation flick, without the exploitation. And released in the early 80s (but from what I understand, it was actually shot in the late 70s).
Runaway Nightmare tells the "story" of two worm farmers (one of 'em played by director Mike Cartel) who get abducted by this female cult. Then a whole bunch of nothing, and then they help the cult with, something? It really doesn't matter too much to be honest.
Unfortunately this wasn't the mind bogglingโฆ
