Danielle Breton (Margot Kidder) is a model and would-be-actress hired to pretend that she is a blind woman so that an insurance seller Philip Woode (Lisle Wilson) would have to decide if he is going to look her undressing or not as part of The Peeping Toms, a hidden camera program. He doesn't look to her at the changing rooms of his gym, so both win a prize in the program. Philip wins a dinner-for-two at the African Room restaurant, and Danielle wins a cutlery set. After the program, Danielle and Philip seem to hit it on, so Philip invites her to the dinner.At the restaurant, they are interrupted by Danielle's ex-husband Emil Breton (William "Bill" Finlay), but Philip makes him be overthrown from the restaurant. Later, Danielle and Philip go to the former's apartment in Staten Island. The ex-husband follows them, so that Philip has to leave the apartment, make believe that he's leaving for good, and then return through the back door. When he comes back, Philip opens the door with Danielle's keys, and at the same time he gives her the cutlery gift - which Danielle had left in his car. Philip and Danielle make love in the couch of the living room.The next morning Danielle wakes up and she isn't feeling that well. She goes to the medicine box in the bathroom and checks that there are only three red pills left. She takes one immediately and leaves the other two in a corner of the washbasin. However, when Philip also wakes up and dresses himself, he throws the other two pills down the sink. Philip overhears Danielle and her sister Dominique fighting and arguing (in French) about him. Danielle says she isn't feeling that well, and would Philip go for more red pills to the chemist's? Philip complies and loses more time because he wants to buy a present for Danielle and her twin sister Dominique, who is supposedly visiting Danielle - although during the game show she said that she was dead.Philip returns to the apartment and unlocks the door with Danielle's key again. She takes the big knife from the cutlery set and offers it to Danielle to cut up the birthday cake. However, she uses the knife to viciously kill him. Philip crawls trying to call her neighbor's attention - her window is a bit higher but close enough for both tenants to see each other. Philip even tries to write "HELP" with his blood on the window.The neighbor is Grace Collier (Jennifer Salt) a journalist, who usually writes about the state of things in Staten Island, sometimes to criticize the police officers and their use of violence. So Detective Kelly (Dolph Sweet) is not very kind towards Grace's agitation. Meanwhile, Danielle wakes up confused and dazzled. She has tried to talk to her doctor, who promises to bring her more of the red pills.Emil comes up to the apartment. Danielle opens the door, still feeling sleepy. When Emil points to the corpse behind, Danielle says that Dominique was there. Emil, who is at the same time Danielle's doctor and the provider of pills, cleans the apartment while Danielle dresses up. They put the corpse inside the bed-sofa. Emil laves and takes the bloodied knife away. When Detective Kelly and Grace appear, there is not a stain in sight. Danielle is kind, and the only remains of the corpse is a red stain on the back of the futon where Grace is sitting. Danielle justifies the double sets of matching clothes due to her job as model, because if one of them gets stained, they would have an identical outfit available. Grace finds the cake in the fridge. Also, Danielle had said that she lives on her own, and that's the opportunity for Grace to prove that she is lying. However, Grace falls down and smashes the cake against detective Kelly's leg. Emil appears, saying that they are separating, but that they are not divorced.Detective Kelly tells Grace not to disturb him or Danielle again with that matter. The only clue Grace has got at this moment is that she has read the name of the bakery where Philip bought that cake. She had a date with her mother, annoying Mrs Collier (Mary Davenport), who mentions a new open-door psychiatrist hospital which has been opened in Staten Island. But Grace is not listening to her. When they arrive at the bakery, she jumps to ask the shop assistants (Olympia Dukakis and Justine Johnston), but the only thing she learns is that there was a black man who had bought that particular cake dedicated to Danielle and Dominique on their birthdays.Grace hires a private detective called Joseph Larch (Charles Durning), who says that the only possibility of hiding a body is within the sofa. Grace tells him that he has found the Blanchion Siamese twins, but the detective says that he didn't see any twins, he has only found a place in which a human body could be hidden without the police finding it.Grace talks to a doctor, Arthur McLennen (Barnard Hughes) who studied the case of the Blanchion Siamese twins, the first set of twins of Canadian origin. Dr. Pierre Milius - Emil's younger persona - appears on a news report talking about the delicate psychological mental equilibrium of one of them. As teenagers, Danielle is shy, but Dominique is more talkative and shows off more. McLennen says that, because of the official silence, he had bribed one of the nurses who helped during the surgery, and that nurse told him that there complications had arisen during the process, resulting in Dominique's death.Larch keeps on watching the strange movements in Danielle's apartment. When movers arrive to take the sofa away, he tells Grace that he overheard the movers saying they are going to take it away to Canada to a remote location, and he leaves to follow the sofa to it's destination and tells her to continue to keep an eye on Danielle.That evening, Grace follows Danielle to the hospital. There, she overhears a discussion of Emil and Danielle having a row, because she's fed up being controlled. She sees how she puts an injection to her, forcibly. Grace tries to use the phone, but one of the interns prevents her. Arlene (Cathy Berry), the crazy patient, says that viruses and bacteria go through the telephone line, and that she got sick because of answering the phone. A hospital attendant (Burt Richards) asks his boss to see to the problem. Emil tells Jansen, the hospital attendant, that she's the new patient, Margaret, and that she should be put in a room. Grace tries to explain, but it's useless; she's not believed. Emil hypnotizes her so that she will believe that the murder that she witnessed and everything was a strange dream of hers.Grace appears now on the dreams/reminiscences about Danielle's life while attached to Dominique. Danielle suffered because when she started to be in love with her doctor, she realized that her twin sister will not accept the risk of surgery, and that she will not accept her being in love with somebody else either.Grace wakes up and screams. Danielle also wakes up, dazed. She wants Dominique back, but she is also afraid of her attacking Emil. Emil says that every time he tried to make love to Danielle, Danielle became Dominique, furious and enraged. Danielle tries to run away from Danielle. He shows her the knife, still bloodstained. Danielle - possibly thinking she's Dominique - picks up a scalpel and cuts Emil's skin. Emil tries to kill Danielle, but he bleeds to death instead. All this happens in the presence of a dizzy Grace who wakes up in time to see Danielle hugging a dead Emil, still bleeding. Grace screams.Emil is taken away in an ambulance, dead. Danielle denies that she has killed anyone in her life, and she also states that her sister died last spring. Grace Collier is taken away, dazed and confused.Some time afterward, Detective Kelly tries to talk to recovering Grace. Danielle has confessed to killing Emil, but he admits that they have problems to determine who the missing black man could be. However, Grace repeats what Emil has taught her through hypnotism: that she couldn't have possibly seen such a corpse because there was no murder to begin with, and her mother supports her. Grace's mind has indeed been completely wiped by Emil who has 'programed' her not to remember the murder of Philip Woode.In the final scene, the shrouded sofa, with Phillip Woode's dead body still inside it, arrives at a semi-abandoned semi-derelict countryside train station in rural Quebec, Canada, with a cow chewing peacefully nearby. Nearby, Joseph Larch watches the sofa from a telephone pole, thinking that some day the culprit will arrive to get rid of the sofa and the body for good. But he is unaware that Emil is dead, and that Grace's mind has been erased of all memories about the killing. Larch continues to wait and wait for someone (who will never arrive) to claim the sofa with the dead body inside it.
Storyline
The Staten Island apartment of lovely model Danielle becomes the scene of a grisly murder that is witnessed by her neighbor Grace, a reporter. But the police don't believe her story, so it's up to Grace to solve the murder mystery on her own. — alarmanwp Grace Collier is a columnist with the Staten Island "Panorama". She generally works on fluff pieces, but on occasion is allowed to do hard-hitting stories which she prefers. From her apartment window one morning, she sees what she is certain is the stabbing murder of a Black man by a White woman in an apartment across the way; the Black man, seeing her, tried to scrawl the word "help" in his own blood on the window. Reporting what she saw to the police, Grace gets little help from them, who think little of her because of previous stories she has written on police brutality and racism. When the police and Grace arrive at the apartment in question, they find no dead body, no blood, and no woman matching the murderer Grace saw. All they find is the tenant, Danielle Breton, a young French-Canadian model/actress, who is visited by her soon-to-be ex-husband, Emil Breton. However, what Grace saw truly did happen, the dead man being Phillip Woode, a man Danielle just met on her latest job on a game show and her sex partner for the evening, and the murderess being Danielle's possessive twin sister, Dominique Blanchion. Emil helped Danielle cover up the murder. Grace, with the help of a private investigator named Joseph Larch, tries to find out what is going on, including where the dead body is, which Grace believes they could not have moved out of the apartment between the time she saw the murder and when she and the police initially arrived on the scene. If Grace and Larch find out the truth, they will learn of an unusual relationship between Danielle, Dominique and Emil, one with strong psychological overtones based on the scar Danielle has on her right hip. And even if Grace and/or Larch discover the truth, they may not survive what Emil is willing to hide at any cost to protect Danielle. — Huggo Margot Kidder is Danielle, a beautiful model separated from her Siamese twin, Dominique. When a hotshot reporter (Jennifer Salt) suspects Dominique of a brutal murder, she becomes dangerously ensnared in the sisters' insidious sibling bond. A scary and stylish dissection of female crisis, Brian De Palma's first foray into horror voyeurism is a stunning amalgam of split-screen effects, bloody birthday cakes, and a chilling score by frequent Alfred Hitchcock collaborator Bernard Herrmann. — Anonymous Danielle Breton and Phillip Woode meet on a game show and a relationship blooms. They go back to her apartment on Staten Island. The next morning Phillip is brutally murdered in the apartment, an event witnessed by a neighbour, reporter Grace Collier. She calls the police but when they arrive there is no sign of a crime. She is undeterred, however, and determined to bring the murderer to justice. — grantss 1 more See all
