Outwardly a deeply religious, highly principled woman, Melanie Leroy (Talia Shire) will stop at nothing to have the perfect husband and family. This horror outing recounts the grisly lengths to which she goes to achieve this. As the story begins, she is happily married until she discovers that her husband has been having an affair. Something snaps inside, and she murders him. Soon after, she inherits an apartment building from a recently deceased aunt and becomes the landlady. Unfortunately, she has a low tolerance for tenants who break the rules, and those who disobey are murdered in devious and ingenious ways. Matters reach their deadly climax when she becomes obsessed with the tenant whom she believes will fulfill all her dreams. ~ Sandra Brennan, All Movie Guide
