IT'S SHOCKING! IT'S BEYOND YOUR IMAGINATION!
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.
If you've never seen it and aren't sure you can take a movie THIS BAD, I highly recommend the MST3K screening. I think Tubi has it for free, and it's way more bearable with the jokes instead of say... seven minutes of watching people drive in silence. Probably my favorite episode.
