Christoper Lambert stars in this post-apocalyptic future story based on the 8th century Saxon epic poem about the knight who battled a monster in a medieval castle. In this story, Beowulf is a wanderer who learns about a man-eating creature called Grendel which comes in the night to devour warriors trapped at the Outpost. The Outpost is ruled by Hrothgar (Oliver Cotton). He has a daughter (Patricia Velasquez), whose husband may have been murdered by the Outpost's master of arms (Goetz Otto).
