Context of the Movie
Its all about one ring and the future of civilization rests in the fate of the One Ring, which has been lost for centuries. Powerful forces are unrelenting in their search for it. But fate has placed it in the hands of a young Hobbit named Frodo Baggins which was played by Elijah Wood in the movie, who inherits the Ring and steps into legend. A daunting task lies ahead for Frodo when he becomes the Ringbearer - to destroy the One Ring in the fires of Mount Doom where it was forged.
Short Story
The story begins in the Shire, where the hobbit Frodo Baggins inherits the Ring from Bilbo Baggins, his cousin and guardian. Neither hobbit is aware of the Ring's nature, but Gandalf the Grey, a wizard and an old friend of Bilbo, suspects it to be Sauron's Ring. Seventeen years later, after Gandalf confirms his guess, he tells Frodo the history of the Ring and counsels him to take it away from the Shire. Frodo sets out, accompanied by his gardener, servant and friend, Samwise "Sam" Gamgee, and two cousins, Meriadoc "Merry" Brandybuck and Peregrin "Pippin" Took. They are nearly caught by the Black Riders, but shake off their pursuers by cutting through the Old Forest. There they are aided by Tom Bombadil, a strange and merry fellow who lives with his wife Goldberry in the forest.
The hobbits reach the town of Bree, where they encounter a Ranger named Strider, whom Gandalf had mentioned in a letter. Strider persuades the hobbits to take him on as their guide and protector. Together, they leave Bree after another close escape from the Black Riders. On the hill of Weathertop, they are again attacked by the Black Riders, who wound Frodo with a cursed blade. Strider fights them off and leads the hobbits towards the Elven refuge of Rivendell. Frodo falls deathly ill from the wound. The Black Riders nearly capture him at the Ford of Bruinen, but flood waters summoned by Elrond, master of Rivendell, rise up and overwhelm them.
Frodo recovers in Rivendell under Elrond's care. The Council of Elrond discusses the history of Sauron and the Ring. Strider is revealed to be Aragorn, Isildur's heir. Gandalf reports that Saruman has betrayed them and is now working to become a power in his own right. The Council decides that the Ring must be destroyed, but that can only be done by sending it to the Fire of Mount Doom in Mordor, where it was forged. Frodo takes this task upon himself. Elrond, with the advice of Gandalf, chooses companions for him. The Company of the Ring are nine in number: Frodo, Sam, Merry, Pippin, Aragorn, Gandalf, Gimli the Dwarf, Legolas the Elf, and the Man Boromir, son of Denethor, the Ruling Steward of the land of Gondor.
After a failed attempt to cross the Misty Mountains through the Redhorn Pass, the Company are forced to take a perilous path through the Mines of Moria. They are attacked by the Watcher in the Water before the doors of Moria. Inside Moria, they learn of the fate of Balin and his colony of Dwarves. After surviving an attack, they are pursued by Orcs and by an ancient demon called a Balrog. Gandalf faces the Balrog, and both of them fall into the abyss. The others escape and find refuge in the Elven forest of Lothlórien, where they are counselled by its rulers, Galadriel and Celeborn.
With boats and gifts from Galadriel, the Company travel down the River Anduin to the hill of Amon Hen. There, Boromir tries to take the Ring from Frodo, but Frodo puts it on and disappears. Frodo chooses to go alone to Mordor, but Sam guesses what he intends and goes with him.
