There, her brother killed the entire family, with Beth narrowly escaping with serious stab wounds. Well, she's got a point there. I can remember the musky scent of the pony we got for Christmas, and the colors of the tulips my grandmother planted, and where I was the first time I saw Kansas City Bomber . But that time my brother massacred the entire family didn't stick out in my memory palace that well. No doubt Sorority House Massacre will quickly fade from my memory, too.
Experienced viewers can probably fill in the rest of the plot from there.
The dream sequences allow Frank's Kubrick-like symmetrical sense of composition come into play. The girls plan a party, inviting over some boys to up the body count, including that cute guy Beth's had her eye on. The police are notified that Bobby Henkel is on the loose, but no one goes looking at his old house, or thinks to check on his sister. Why Slumber Party Massacre , of course. Bobby continues to pick off victims, and sorority girls run from one room to another in their nighties for, oh, the next fifty minutes.
