A young man visiting a carnival becomes the latest victim of an evil fortune teller, who turns men into monsters who kill whomever she pleases.

Director Ray Dennis Steckler's picture, in which according to IMDB he also stars under the pseudonym Cash Flagg, is a weird amalgam of a movie, in which the horror sequences are frequently interrupted by filmed musical numbers being performed in the carnival setting.  The music sequences seem random, not commenting on the action in any way, and although some care was put into the choreography, the performances are filmed matter-of-factly, making it seem like Steckler captured them live on camera, and then edited them individually into his movie.  As a horror film, even if you forget the musical scenes, you're more likely to laugh than shriek at the results, in particular at odd shots of carnival puppetry and loopy camera movement during the hypnosis scenes.  Still you can't help but be entertained by this mess of a movie.
