Frank Booth is the central villain in David Lynch's landmark Blue Velvet. Booth is depicted as an extremly troubled, mentally disturbed man who has obviously suffered from a terrible upbringing. A violent sadist with a taste for torture and rape, Booth is the central figure to his hometown of Lumberton, North Carolina's (fictional) underworld of drugs, murder and prostitution. At the start of the film, he has been steadily taking over Lumberton's drug trade by having all of his rivals murdered. One of his henchmen, a corrupt homicide detective known only as The Yellow Man, then steals the dealer's drugs from the crime scenes and clandestinely transfers them to Booth, who then sells them off.His empire's most prized asset is Dorothy Vallens (Isabella Rosselini), a beautiful, somewhat disturbed torch singer who brings huge crowds into the local nightclub, The Slow Club , and whom he takes complete control over when he kidnaps her son and husband. He extorts sadomasochistic sexual favors from her by mutilating her husband and threatening to kill the child if she doesn't give in to his sexual advances. He insidiously makes her his slave, to the point that, after pretending to enjoy his abuse for so long, she begins to derive masochistic pleasure from it.Frank is depicted as having scores of mental problems. During a typical night with Dorothy, he repeatedly switches back and forth between two personas, baby and daddy, the former of which violently beats Dorothy and verbally degrades her, and the latter of which brutally rapes her while sobbing and crying like a child, often calling her mommy during the rape. At two other points in the film, Frank is depicted as crying uncontrolably; once, while listening to Dorothy sing Blue Velvet (during which he only weeps but makes no sounds) at the Slow Club and a second time while watching one of his henchmen lip-synch to Roy Orbison's In Dreams. During this sequence, Frank at first merely weeps, then begins to sob uncontrolably and bawl, until he abruptly flies into a fit of rage and demands the song be shut off. The reasons for Frank's personalities and uncharacteristic displays of emotion are never explained throughout the film, although a theory is offered as to his obession with Dorothy.Frank's criminal empire is threatened by college student Jeffrey Beaumont (Kyle MacLachlan), who, one day while walking, finds one of Dorothy's husband's severed ears, which Frank pressumably dropped after having cut it off with a pair of scissors as a warning to Dorothy. Jeffrey quickly becomes obsessed with the case, going so far as to break into Dorothy's apartment and search for clues, where he witnesses Booth raping her from inside a closet. At first, Booth writes Beaumont off as a mere nuisance, so he and his cronies simply rough him up just to send a message, and occasionally taunt him. Beaumont tells his girlfriend's father, the local police detective, what has been going on. The police detective instructs Jeffrey not to involve himself any further, but he later defies that order and sets out rescue Dorothy's son after Booth beats Vallens nearly to death, strips her naked, and leaves her in front of Beaumont's house. Jeffrey rushes to Vallens' apartment in hope of rescuing her son, and is met with the horiffic scene of Dorothy's husband, bound to a chair and shot in the head, and the Yellow Man, whom Frank has crudely lobotomized. Booth flees to the apartment after the police raid his own home, and overhears Jeffrey calling for help on the police radio. Realizing that Frank is coming for him, Jeffrey intentionally gives the police false information as to his whereabouts, so as to throw Frank off his trail. Frank enters the apartment, kills the Yellow Man, and then seeks out Jeffrey, who has enough time to steal the Yellow Man's gun; when Frank eventually finds Jeffrey, Jeffrey fatally shoots him in the head - killing him.
