A sense of claustrophobia fills the film, as the darkly painted rooms inside the house contrast with the Southern California sunshine streaming in through the windows. Kornhauser builds both suspense and sexual tension as the events progress, punctuating the story with title cards showing dates from the religious calendar that add a timeless, otherworldly quality to the goings on. And when the action erupts, it's startling and very disturbing. This isn't a perfect film--the plot is a bit convenient at times, requiring a slight logical leap at the end--but it builds its atmosphere so nicely that it's a film well work looking out for.
