The epic poem gets a reboot. Hrothgar, the Danish king, has murdered the troll who has been terrorizing his lands. But he cannot bring himself to murder its son, Grendel, who grows up to be a terror as well. In order to save his kingdom, Hrothgar calls on his best hero, Beowulf, to kill Grendel. As he searches for the monster, Beowulf comes across such obstacles as the witch Selma who cannot decide between Beowulf and the monster himself.
