In this genre-defying grind-house throwback, a group of drug-fueled, 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.
Inspirations for the film include counter-culture American icons such as Roger Corman, Russ Meyer and Dennis Hopper. Shock cinema, with a tongue-in-cheek, humorous attitude is a hallmark of independent cinema in the USA and Someone's Knocking At The Door brings that philosophy to a new generation of socially conscious and intellectual viewers. Satire of sex, drugs and rock n' roll abounds, with a particular look at the US culture of consumption, the medical community and follies of youth. With a hip, youthful score and fringe dynamics, the film brings an avant-garde, contemporary spin to a classic genre.
