Nightmare Weekend (ej svensk text) (Blu-ray)

Behind Julie Clingston's pretty face lies a devilish brain. Three young college girls are to become her victims. She invites the girls and their friends to the remote house of Professor Brake and wants to test the latest, most modern horror machine on them. Clingston's computer, called "Apache," can fire small silver bullets that lodge in the minds of the visitors and cause horrible changes. Victims go insane, hair falls out, eyes bulge out, faces mutate into gruesome grimaces. Eventually, the skin begins to melt. When Jessica, the professor's young daughter, comes home, she wants to help. She has to activate her computer against "Apache". There are only seconds left before the hideous mutants pounce on her.
