A family gets lost on the road and stumbles upon a hidden, underground, devil-worshiping cult led by the fearsome Master and his servant Torgo.
Objectively, it's one of the worst films ever made. It seriously makes The Room look like a Scorsese-directed masterpiece. But it's such a hilarious mess that I have to give it a full 5 stars. I got too much enjoyment out of it to give it any less than that.
