Someone's Knocking at the Door (2009) mp4

The shocking news of the gruesome, sex-related homicide of medical student, Ray Harris, spreads like wildfire in the Linda Vista Community Hospital. Was it a deviant S&M game gone wrong or is there, indeed, a deranged serial killer lurking in the campus? As the police investigation continues, a strange connection between the highly experimental hallucinogen, Taldon, and the peculiar 1973 case of John and Wilma Hopper emerges, while Ray's friends, start being stalked by a pair of insane sociopaths who have only one intention: to ravish them to death. And, before long, warm, bright-red blood will flow. Is there an escape when the enemy lives inside one's head?
