The Last House On The Left (1972 Film) - Plot

Plot

Mari Collingwood plans to celebrate her 17th birthday by attending a concert with her friend, Phyllis Stone. Her parents, Estelle and John, express concern both at the band and Mari's friendship with Phyllis. They let her go, giving her a peace symbol necklace as a gift before she leaves.

Phyllis and Mari go to the city for the concert. On the way, they hear a news report on the car radio of a recent prison escape, involving criminals Krug Stillo, a rapist and serial killer, his son Junior, Sadie, a promiscuous psychopath and sadist, and Fred "Weasel" Podowski, a child molester, peeping tom, and murderer. Before the concert, Mari and Phyllis stroll the streets, seeking someone who might sell them marijuana. They find Junior, who leads them back to an apartment, where they are immediately trapped by the criminals. Phyllis tries to escape, then tries to reason with the criminals, but fails and is gang-raped by Krug, Weasel and Sadie. Meanwhile, Mari's unsuspecting parents prepare a surprise party for her.

The next morning, the two friends are locked in a car trunk and taken to the countryside as the gang intends to leave the state. The villains' vehicle malfunctions right in front of Mari's house while police are in her home talking to Mari's parents about her disappearance. Removed from the trunk, Phyllis is beaten as Mari realizes that they are near her own home while she is dragged to the woods. In the woods, both teenagers are untied. Mari and Phyllis are forced to have sex with each other and then Sadie performs oral sex on a weeping Mari. Phyllis runs away to distract the kidnappers and offer Mari an opportunity to escape, but is chased by Sadie and Weasel, while Junior stays behind to guard Mari, who tries to convince Junior that her father can help him, and she gives him her peace symbol necklace as a symbol of her trust. Phyllis manages to hit Sadie in the face and runs, but is then cornered and stabbed to death by Weasel. Sadie reaches into Phyllis's wounds and pulls out the insides, while Krug and Weasley amputate the hand and half of the forearm.

Mari eventually convinces Junior to let her go, but they are immediately halted by Krug. Sadie and Weasel present Phyllis' severed hand and half forearm and Krug proceeds to carve his name into Mari's chest. As Mari screams in pain, Krug tells her that she's gonna "get yours" at which point he pulls down Mari's pants and rapes her. Soon after this act, Mari vomits. At this point, the gang very briefly feel pangs of conscience. Mari quietly says a prayer then walks into a nearby lake. Krug shoots Mari and she floats on the top of the lake. Krug, Sadie, and Weasel wash and change out of their bloody clothes.

In their new attire, the gang go to the Collingwoods' home, masquerading as traveling salesmen. Mari's parents agree to let them stay overnight. Junior exposes their identity when Mari's mother, Estelle, sees Mari's peace symbol necklace dangling around his neck. Later that night she listens in to the gang while they are spending the night in Mari's bedroom and finds blood-soaked clothing in their luggage. She and Dr. Collingwood rush out into the woods, where they find Mari on the bank of the lake. They carry Mari's body back to the house then exact revenge against the crooks.

Outside, Estelle dupes Weasel into a sex game, then performs fellatio on him. Without warning, she bites off his penis and leaves him to bleed to death. Inside the house, Dr. Collingwood carries his shotgun into his daughter's bedroom, where two of the criminals are sleeping. Krug escapes into the living room and overpowers the doctor, but the criminal is then confronted by his own son, who now brandishes a firearm and threatens to kill him. Krug psychologically manipulates the already troubled young man, demanding him to put the gun in his mouth and blow his brains out. Junior then shoots himself in the head. Then Krug finds out the doctor has disappeared.

Sadie rushes outside where she is tackled by Estelle. The two of them wrestle and fight on the ground. Sadie punches Estelle and runs away. She then trips and falls into the pool. Estelle grabs a knife and pulls Sadie up and cuts her throat open, killing her. The doctor kills Krug with the chainsaw and the couple meet each other again in the living room as the police come.
