Grendel

King Higlack of the Gauths entrusts prince Finn and a fire ball weapon to his champion, slayer Beowulf. They lead twelve men on a mission to help king Hrothgar of the Danes, whose once glorious realm is terrorized by undefeated the Biblical monster Grendel. In fact the task is even harder, as Hrothgar kept gruesome secrets. (imdb)
