An epic tale based on the famous Old English poem, "Beowulf," which inspired Tolkien's "Lord of the Rings". The medieval adventure, part fable, part horror story is loosely based on the 9th century Anglo-Saxon poem, "Beowulf," telling the blood-soaked tale of a Norse hero's battle with a great and murderous troll.

Venting a life long grudge against the men who killed his father, monstrous troll Grendel embarks on a murderous campaign against a Danish settlement whose besieged king beseeches the aid of legendary warrior Beowulf.

When Grendel returns to wreak his nightly slaughter in the king's great hall, Beowulf and his band of monster slayers are ready and waiting. But the sly troll evades his ambushers by fleeing into his labyrinthine cave and Beowulf resorts to an ignoble trick, luring him out with hostage Selma, a town outcast who strangely doesn't fear Grendel and who shares with the creature a mysterious congress. When Beowulf slays the vengeful troll in a grisly, bloody engagement, Selma mourns while the others rejoice. However, the revelry is short lived as Grendel's mother, the even more terrifying Sea Hag begets her own revenge.

Hunting the sea creature to her lair beneath the ocean, Beowulf discovers the startling secret connecting Selma to Grendel and battles the fearsome Sea Hag in a confrontation that will commit his name to legend for the ages.
