DVD Description: Time to party hardy. Hardly! It's more like time to bail when two psychotics gate-crash a perfectly delightful get-together and turn it into a gore-fest with a huge body count. Directed by Ruggero Deodato, House on the Edge of the Park makes no pretense -- it's an exploitation flick complete with ritualistic torture.
