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.

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.
