(The complete plot for this South Park Episode)
The episode starts with Stan, Kyle, Cartman, and Kenny who is actually using Cartman's body, playing "The Lord of the Rings. Randy and Sharon (Stan's parents) have rented the movie The Lord of the Rings. They tell Stan, Kyle & Cartman to bring it to Butters' parents, as they had asked to borrow it. Still caught up in their game, the boys see this assignment as a "quest", and set off on their journey. When the boys leave, Stan's parents try to watch a big-time adult movie. When they play the tape they discover that Randy accidentally mixed up the movies, and realize that Butters is now watching it at his house.The two drive to Butters' house, and come across the boys returning home, having already delivered the tape. Stan's father plays into the boys' imagination and sends them on their greatest quest ever: retrieve the tape, as it "holds an evil power." Excited, the boys eagerly comply and set off toward Butters' house. They arrive and take the tape, but not before discovering that Butters, though not realizing the nature of it, has watched the movie and becomes obsessed with it, even wondering aloud, "What's going on down there?" before the other boys arrive. Excluded from the game and denied the video, Butters becomes steadily more insane, and remains secluded in the basement, muttering about his "precious" and generally acting like Smeagol (from the movie "Lord of The Rings). At this point the Marshes, who have grown worried that the boys have not returned, show up. Distraught at Butters' behavior, they assume that the boys now have the tape and are watching it. Contacting the other parents, they go on a desperate search to find their missing children and "put it into context."
On the way back home, our boys run into 6th graders, who look inside the box and realize what kind of movie is on the tape. Although they try to take the tape, the boys are able to escape and decide to take it to the council of the High Elf of Faragon who, in fact, is Clyde. At the council, at which most of the fourth-graders are present, it is decided that to determine the tape's power, they should send one of their own to watch it for a few minutes. Talangar the Black (who, in fact, is Token) is volunteered, and steps inside his house for a moment. He soon comes out, expressionless, and announces that he's not playing anymore without an explanation. Now truly convinced of the tape's power, the council decides the tape must be returned to the Two Towers video store "from whence it came", and forms the "Fellowship of The Lord of the Rings", which consists of Stan, Kyle, Cartman with Kenny, Craig, Jimmy, and an unnamed kindergartener, who is believed to be Filmore.
The boys avoid a run-in with the 6th graders but their party loses Jimmy, Craig, and the kindergartener. Butters, who has been following them, offers to guide the remaining party members to the store in a thinly veiled attempt to get the tape back. Soon all the boys wind up at the Two Towers, and with the 6th graders in hot pursuit they desperately try to return the tape to the drop box.
When Butters refuses to let go of it, Kyle throws him and the tape into the drop box. Angered at losing their movie, the 6th graders threaten to beat the boys up, but flee when the parents arrive. The parents then go into a long discussion with the boys, on subjects not appropriate for their age.
Our boys, who have actually never watched the tape remain speechless.
In the and of the episode we have Butters holding his "precious" among a pile of other returned tapes in the drop box. An epic ending, I might add.
