Sickening 1960’s precursor to the “Saws” and “Hostels” of today’s sadomasochistic cinema. An invalid gets trapped in her elevator after an electrical mishap shuts off the power in her house. It’s not long after this that a collection of cruds break in to her place and indulge in unpleasant behavior. A wino, a floozy, and a trio of psychotic hipsters make the place their own and spread the mayhem. James Caan in an early, evil role. Shot in very bland, claustrophobic black and white. You’ll feel damaged by the time this thing is done.
