Inspired by the epic poem Beowulf, Kid Beowulf follows the journey of 12-year-old twin brothers, Beowulf and Grendel, as they travel to distant lands and meet fellow epic heroes therein. Beowulf and Grendel are in war-torn Spain, where honor is hard-fought, allegiances are dubious, and the bulls run wild. Amidst it all comes a young knight named Rodrigo, who fights for the name he's lost, the land he loves, and the virtue they've both forgotten.
