A great piece of grindhouse cinema that was released to drive-ins on a double bill with Last House on the Left.
A nurse (Rosie Holtik) arrives at an insane asylum out in the middle of nowhere for a new job. What she doesn't know is that the asylum director Dr. Stephens got chopped on with an axe by an inmate and is down in the basement. She also doesn't know that Dr. Geraldine Masters is just another crazy person posing as the head of the insane asylum. Eventually all the other patients get mad at Geraldine and go at her with a bunch of sharp instruments. Rosie Holtik escapes.
Thanks Don P!
