King Hrothgar of Denmark, enjoys a prosperous and successful reign. He builds a great mead-hall, called Heorot, where his warriors can gather to drink, receive gifts from their lord, and listen to stories sung by the scops, or bards. But the jubilant noise from Heorot angers Grendel, a horrible demon who lives in the swamplands of Hrothgar's kingdom. Grendel begins terrorizing the Danes every night, killing them and easily defeating their efforts to fight back. The Danes suffer many years of fear, danger, and death at the hands of Grendel. Eventually, however, a young Geatish warrior named Beowulf hears of Hrothgar's plight. Inspired by the challenge, Beowulf sails to Denmark with a small company of men, determined to defeat Grendel. Hrothgar accepts Beowulf's offer to fight Grendel. During a feast, one which Beowulf is attending, Grendel shows up and challenges Beowulf. Beowulf fights him unarmed, proving himself stronger than the demon, who is terrified. As Grendel struggles to escape, Beowulf tears the monster's arm off. Mortally wounded, Grendel slinks back into the swamp to die. The severed arm is hung high in the mead-hall as a trophy of victory. After Grendels defeat, Grendels mother comes to Heorot and seeks revenge for her son's death. Beowulf dives into the swamp and fights Grendels mother. He kills her with a sword, and cuts her head off and brings it as a trophy. Beowulf ascends to the throne of the Geats. He rules wisely for fifty years, bringing prosperity to Geatland. When Beowulf is an old man, however, a thief disturbs a barrow, or mound, where a great dragon lies guarding a horde of treasure. Enraged, the dragon emerges from the barrow and begins unleashing fiery destruction upon the Geats. Sensing his own death approaching, Beowulf goes to fight the dragon. With the aid of Wiglaf, he succeeds in killing the beast, but at a heavy cost. The dragon bites Beowulf in the neck, and its fiery venom kills him moments after their encounter.
