Synopsis
Killer Nun (1978) was produced in Italy. It features Anita Ekberg as Sister Gertrude, who is recovering from neurosurgery, although her Mother Superior (Alida Valli) dismisses Sister Gertrude's fears about rushed recovery. Unfortunately, soon enough, it becomes clear that Sister Gertrude's fears were legitimate, as the hapless nun spirals into psychosis and addiction to morphine and heroin at the geriatric hospital where she works.
As well as initiating a lesbian affair with Sister Matthieu (Paola Morra), Sister Gertrude expels concerned Dr Patrick Roland (Joe Dallesandro) from the hospital, and a reign of terror is initiated, in which Sister Gertrude inflicts humiliating calisthenics on one group of elderly inmates, stomps on an elderly woman's dentures, reads gory hagiographic details of the lives of tortured saints to her hapless charges and is judged to have thrown an elderly man engaged in sex with a nurse out of a window. As if this weren't enough, Sister Gertrude goes into a nearby town, picks up a man at a bar, and has impersonal heterosexual sex as well. Finally, the Mother Superior is convinced that she must do something about the aberrant behaviour of Sister Gertrude... but is she really the perpetrator of murder, or is someone trying to frame her?
