When seven sorority girls plan a graduation party their over strict den mother says “no”.  In retaliation for this injustice the girls play a prank on the old hag that goes too far and leaves her dead of a heart attack.  Fearing jail time and lacking good sense the seven girls hide the body in the filty swimming pool, unaware that her disfigured and quite insane son has escape his imprisonment in the attic, dressing up like his late mother, he stalks and kills the seven girls and her unlucky party guest using her old cane as a stabbing weapon (which is way too sharp for real, I mean how could she hold the can without cutting her hand to ribbons.)SPOILER WARNING! IF YOU DON’T WANT IT SPOILED THEN STOP READING: It ends with all but one killed horribly and she has been stabbed repeatedly totally unaware that the maniac is alive and opened one eye.  Plus what’s worse you never get a good look at the so-called deformed child cruelly locked in the attic, I mean no matter how ugly or deformed the child is, what mother would lock her son in the attic.  Plus the maniac son in the attic has been done to death people.  If you are headed for the house on sorority row, I would suggest that you keep on passing by.
