Silent Madness 3D 01/21 Blu-ray (Rental)

Thanks to a computer glitch, hulking and homicidal Howard Johns (Solly Marx) was discharged from the institution-and he headed for the upstate sorority house where he went on a bloody rampage a generation ago. Psychiatrist Joan Gilmore (Belinda Montgomery) gives chase to try to head off more campus carnage-and she faces as much danger from the hospital's ruthless cover-up as she does from Howard. Shocker also stars Viveca Lindfors, Sydney Lassick. 93 min.
