In ancient times the Rings of Power were crafted by the Elven-smiths, and Sauron, the Dark Lord, forged the One Ring, filling it with his own power so that he could rule all others. But the One Ring was taken from him, and though he sought it throughout Middle-Earth still it remained lost to him. After many ages it fell, by chance, into the hands of the Hobbit, Bilbo Baggins. On his eleventy-first birthday, Bilbo disappeared, bequeathing to his young cousin, Frodo, the Ruling Ring, and a perilous quest: to journey across Middle-Earth, deep into the shadow of the Dark Lord and destroy the Ring by casting it into the Cracks of Doom.

Frodo, dostlarının ve müttefiklerinin cesur, kardeşçe yardımları ile çok tehlikeli bir görev üstlenir. Hükmeden efsanevi yüzük'ü yok edecektir. Yüzüğün şeytanı yaratıcısı Karanlıklar efendisi Sauron'un şövalyeleri Frodo'nun peşindedir. Sauron, Hükmeden yüzük'ü geri alacak ve Orta Dünya'ya hükmedecektir.
