Lonnie Knutsengripper is back with a bang! The legendary director and producer of over 300 films is making sure his latest movie is the one they'll remember him for. The Knocking Shop of Horror is the threequel to Lonnie's legendary duo of Interred and The Shithouse Strangler and if you thought those films were controversial then you ain't seen nothing yet baby! This film marks the first time Lonnie has ever made a threequel but as in life or a menage a trois the best things always come in threes.
