Six years later, Janet (Jennie Linden) is a wealthy teenager outcast in a boarding school afflicted by dreadful nightmares and fearing to have inherited her mother´s insanity. After a series of nightmares, her teacher Mary Lewis (Brenda Bruce) brings Janet home and she is welcomed by the family chauffeur John (George A. Cooper), by his wife and housekeeper Mrs. Gibbs (Irene Richmond) and by the beautiful nurse Grace Maddox (Moira Redmond), who was hired as a companion by her guardian Henry Baxter (David Knight). However Janet continues to have nightmares with a woman (Clytie Jessop) with a scar on her face and wearing a white shroud wandering in the house and stabbed on her parents´ bed. After trying to commit suicide, two doctors and Henry summon Janet to the living room to decide whether she should go to an asylum. When Henry brings his wife to the room, Janet sees the woman with scar and stabs her to death. She is sent to an institution and soon a diabolical plot is disclosed. What will happen next?
"Nightmare" is an underrated and unknown thriller by Hammer, with a great story of greed and insanity. The plot is predictable but also engaging. The black and white cinematography and the camera work are magnificent. Jennie Linden never convinces as a teenager but the rest of the cast is excellent. The hysterical behavior of women on the 60´s is annoying but a reality in those years. My vote is eight.
Title (Brazil): "Cilada Diabólica" ("Devilish Entrapment")
