Blue Velvet from Wikipedia:
Blue Velvet is a 1986 American neo-noir, mystery and thriller film written and directed by David Lynch. The film features Kyle MacLachlan, Isabella Rossellini, Dennis Hopper and Laura Dern. The title Blue Velvet is taken from the Bobby Vinton song of the same name.
Set in the small town of Lumberton, North Carolina, the film tells the story of college student Jeffrey Beaumont, who discovers a severed human ear in a grass field behind a neighbourhood. Jeffrey decides to investigate the case himself, with the assistance of Sandy Williams, a high school student and daughter of Lieutenant John Williams, town sheriff. Sandy provides Jeffrey with information she overheard from her father's office which aids them in their investigation of the ear. Jeffrey is eventually drawn into an underworld, home to Frank Booth, a sociopathic criminal, and leader of a gang involved in murder, rape and drug addiction. Blue Velvet opened to widespread critical acclaim and was a box office success, considering its limited release in theatres across the United States. The film earned director David Lynch an Academy Award nomination for Best Director. The film has become a cult classic.
Synopsis: Jeffrey Beaumont (Kyle MacLachlan) returns home from college after his father (Jack Harvey) suffers a near fatal stroke. While walking home from the hospital, he cuts through a vacant lot and happens upon a severed ear and puts it in a paper bag. Jeffrey takes the ear to local investigator Detective John Williams (George Dickerson). When he returns to the Williams house later to discuss the incident further, Jeffrey meets the detective’s daughter, Sandy (Laura Dern). She tells him details about the ear case and a suspicious woman, Dorothy Vallens (Isabella Rossellini). Increasingly curious, Jeffrey devises a plan to sneak into Dorothy’s apartment that involves posing as a maintenance man. Dorothy becomes distracted when a man dressed in a yellow suit (played by Fred Pickler) knocks at her door, and Jeffrey steals Dorothy's spare key.
Jeffrey and Sandy attend Dorothy's nightclub show at the Slow Club. While Dorothy performs at the nightclub, Jeffrey sneaks into her apartment to snoop. He hurriedly hides in a closet when she returns home. However, Dorothy, wielding a knife, finds him hiding and threatens to hurt him. When she realizes he is merely a curious boy, she assumes his intentions are sexual in nature, and is turned on by his voyeurism. She makes him undress at knifepoint, then fellates him. Frank Booth (Dennis Hopper) interrupts their encounter with a knock on the door. Dorothy urges Jeffrey to return to the closet and he then witnesses Frank's bizarre sexual proclivities, which include erotic asphyxiation, fisting, dry humping, and sadomasochistic tendencies. Frank is an extremely foul-mouthed, violent sociopath whose orgasmic climax is a fit of both pleasure and rage. When Frank leaves, a saddened and desperate Dorothy tries to seduce Jeffrey again. She demands that he hit her but when he refuses she demands to be left alone. Jeffrey again observes Dorothy's nightclub show at the Slow Club, where she performs the song Blue Velvet. Frank is also present at the nightclub. Later, in the car park, Jeffrey watches Frank and his cohorts drive away before going to Dorothy's apartment again.
Jeffrey spends the next few days spying on Frank, and at one point sees him entering a building. Shortly afterwards, two men exit the building, a well-dressed man and someone Jeffrey recognizes as the Yellow Suited Man. He concludes the two men are criminals, as is Frank. He also visits Dorothy again, and this time she successfully seduces him. However, while they are making love she asks him to strike her. He refuses and she pressures him, becoming more emotional. Finally in blind rage he knocks her backwards, and is instantly horrified, but Dorothy, as a result of Frank's constant beatings, has come to take pleasure from it.
Afterwards, Frank catches Dorothy and Jeffrey together, and forces them both to accompany him to the typically Lynchian house of Ben (Dean Stockwell), a suave dandy and partner in crime. In a bizarre scene Ben mimes the singing of Roy Orbison's "In Dreams", sending Frank into maudlin sadness, then rage. He takes Jeffrey to a milling yard and savagely beats him to the overture of "In Dreams." Jeffrey wakes the next day and goes home, where he is overcome with guilt and despair. He decides to go to the police. At the police station, Jeffrey notices that Sandy's father's partner is Gordon — the Yellow Suited Man. Later at Sandy's home, her father is amazed by Jeffrey's story, but warns Jeffrey of the danger of the situation. Jeffrey and Sandy go to a dance party together, profess their newfound love and embrace. When they're tailed on their way home, Jeffrey is relieved to discover that it's only Sandy’s football-playing ex-boyfriend. A confrontation is avoided when they see a naked and distressed Dorothy waiting on Jeffrey’s front lawn. Barely conscious, Dorothy accidentally reveals that she slept with Jeffrey, causing Sandy to leave in tears, although she later forgives Jeffrey over the phone.
From the hospital, Jeffrey tells Sandy that he must return to Dorothy's apartment and tells Sandy to send her father there immediately. When he arrives back at Dorothy’s apartment, he finds the crudely lobotomized Yellow Man and dead body of Dorothy’s husband, who is missing an ear. When he tries to leave, he sees The Well Dressed Man coming up the steps and recognizes him as Frank. Jeffrey talks to Detective Williams over the police radio but lies about his location inside the apartment. Frank enters the apartment and brags about hearing Jeffrey's location over his own police radio. When Frank fails to find Jeffrey in the bedroom, he returns to the lounge. Jeffrey shoots Frank with the Yellow Man's gun. Detective Williams arrives with Sandy in tow. Days later, we see Jeffrey and Sandy together, with their lives back to normal, and before the credits, Dorothy and her son playing happily in the park together...
