In this genre-defying grind-house throwback, a group of drug-addled, sexually deviant medical students are systematically terrorized by Wilma and John Hopper. The Hoppers, serial murderers and rapists, mysteriously return from the 1970s, and bring horrifying psychedelia with them. With comedy, subversion, satire and true gore, the students must face escalating attacks, shocking circumstances and visceral disgust. Written by Anonymous

A rapetastic drug trip.
10 December 2011 | by (Australia) – See all my reviews

Got done watching this film, what a fcking trip. There is great production values and some solid acting for this oddity, really bizarre and darkly humorous. The film is essentially about a couple of medical students experimenting with drugs whom or stalked by a serial rapist/murder with a phallus that is 4 inches in diameter and 15 inches in length (so as you can images he fcking anal rapes his victim to death). Now with that plot description you might be expecting one of those doom and gloom type projects that just leave you feeling depressed afterwards, well not so Sally! SKATD is a rather humorous and surreal affair that had me laughing out loud during several of the more bizarre moments and chucking to myself throughout the rest of it. I'm not sure how I feel about the ending, but I guess it was a fun little twist on things and the rest of the film was so much fun anyways so I'm not really bothered by it. Definitely give this one a look, there is lots of fun to be had.
