When a young woman is killed by a shark while skinny-dipping near the New England tourist town of Amity Island, police chief Martin Brody (Roy Scheider) wants to close the beaches, but mayor Larry Vaughn (Murray Hamilton) overrules him, fearing that the loss of tourist revenue will cripple the town. Ichthyologist Matt Hooper (Richard Dreyfuss) and grizzled ship captain Quint (Robert Shaw) offer to help Brody capture the killer beast, and the trio engage in an epic battle of man vs. nature.

Three years after the vampire was destroyed in `Fright Night', his sister - in the guise of a mysterious performer - seeks revenge on the heroic duo who carried out the staking.

A red and white 1958 Plymouth Fury is built on the assembly line. The car injures one worker by slamming its hood shut on his hand; when another one sits in the driver's seat and flicks cigar ashes onto the upholstery, he is subsequently found dead. Twenty years later, nerdy teenager Arnold "Arnie" Cunningham buys the now-decrepit Fury over the objections of his friend, Dennis Guilder. At school, Arnie is bullied by Buddy Repperton and his gang, and Buddy is expelled after threatening Arnie with a switchblade. Defying his parents, Arnie begins to restore the Fury (named "Christine" by its previous owner) at a garage/junkyard owned by Will Darnell. Arnie's appearance and personality begin to change as he works; he sheds his glasses, dresses better, and develops an air of cocky arrogance. His obsession with Christine puts a strain on his relationship with his parents and his friendship with Dennis.

Dennis learns from the seller that the Fury's previous owner was also obsessed with Christine, that his daughter choked to death in the car, and that he and his wife both committed suicide in it. An attractive new student, Leigh Cabot, attends one of Dennis' football games with Arnie; Dennis sees them together and notes that Christine is now fully restored. Distracted, he suffers a severe injury that puts him in the hospital and ends his high school football career. Arnie and Leigh begin a relationship, but Leigh becomes uncomfortable sitting in Christine as the two watch a drive-in movie. The car's radio turns on by itself as Leigh begins to choke on her food, and Arnie finds the doors locked. Leigh eventually frees herself, and another patron administers the Heimlich maneuver to save her life.

Buddy and his gang vandalize Christine in retaliation for Buddy's expulsion. Arnie is so distraught that he angrily breaks up with Leigh when she tries to console him. Once he returns Christine to the garage, he is surprised to see it gradually and completely repair itself. Christine chases down one member of Buddy's gang that evening and kills him, repairing itself again afterward. Police detective Rudy Junkins questions Arnie about the death, but lets him go once Arnie provides an alibi. Later, Christine targets the rest of the gang, killing two members at a gas station and then fatally running Buddy down. The badly damaged car returns to Darnell's garage on its own; when he sits in the driver's seat, Christine kills him by pushing it forward to crush him against the steering wheel. By the time the police find the body, Christine is once more in like-new condition. Junkins again questions Arnie, who becomes angry and gives an alibi.

Leigh asks for Dennis' help to destroy Christine and save Arnie. They plan to lure Christine to the garage and smash it with a bulldozer, but Christine surprises them by emerging from a pile of scrap metal. Leigh flees while Dennis battles Christine, now being driven by Arnie; in an attempt to run Leigh down, Christine crashes into Darnell's office and Arnie is thrown through the windshield, fatally impaling himself on broken glass. Christine continues to attack, repairing itself more quickly than before, until Dennis and Leigh flatten it with the bulldozer.

The next day, Dennis, Leigh, and Junkins watch as the remains of Christine are crushed at the junkyard. Junkins congratulates the teens for stopping Christine, but they regret not being able to save Arnie. The sound of a 1950s rock and roll song spooks them, but it proves to be coming from a boombox carried by a junkyard worker. Christine's front grill twitches slightly.

Twenty years ago, in the sleepy mining town of Valentine Bluffs, a methane gas explosion at Hanniger Coal Mine trapped five miners in a shaftwhen the foremen of the crew left early to attend the town's Valentine's Day dance. Six weeks later, the sole survivor of the accident, Harry Warden, was rescued; he survived by eating his dead coworkers and ultimately had gone mad. After a year in an institution, he escaped on Valentine's Day, killing and cutting out the heart of the guilty foremen, leaving a warning that the same would happen if the town ever again held a Valentine's Day celebration.

With the legend of Harry Warden nothing but a distant memory, a group of young miners and their girlfriends decide that the town has gone without a party long enough. As the night of the dance approaches, a murderous maniac in mining gear begins dispatching townsfolk in bloody and creative ways. The town sheriff and mayor quickly deduce it must be Harry Warden, who was returned to the institution, though their attempts to confirm Warden's status are hindered. Despite the murders, the young adults continue with their plans for a dance, laughing off the "stories" of the murderous Harry Warden. Finally the night of the dance is reached and as the Miner dispatches off several partyers, a group decides to venture into the mines to explore and impress the women. Realizing that a killer is on the loose, a rescue party composed of best friends T.J. and Axel go after the others and Sarah, who both men love.

The Miner has indeed followed them into the mine, killing most of the group, and forcing T.J., Axel, Sarah and Patty to try to escape. Axel appears to be killed and Patty is murdered as well leaving only T.J. and Sarah. On the surface the Mayor and Sheriff have found out that Harry Warden died 5 years ago and are preparing to lead a group of men into the mines. In the mine, the Miner attacks T.J. and Sarah on a moving rail line and the fight eventually is forced into an abandoned shaft where the integrity of the ceiling is in doubt. The Killer is revealed to be in fact not Warden, but Axel. A flashback reveals that he witnessed the murder of his father, one of the foremen, by Harry Warden when he was a boy.

The ceiling then collapses, burying Axel alive. Only his arm is visible, but as rescue efforts are taken it is soon discovered that Axel has cut off his own arm to escape. Through the hole in the wall T.J., Sarah and the police watch as the deranged and delusional Axel runs deeper into the mine calling out to Harry Warden and asking that Sarah be his "Bloody Valentine"
