In 500 CE, Hrothgar, king of Denmark, and a group of warriors chase a large and burly man, whom they consider a troll, and his young son, who already bears cheek and chin whiskers, to the edge of a steep seaside cliff. The father directs his young son, Grendel, to hide from the attackers' view; whereupon The Danes shoot the father dead, and his dead body plunges onto the beach far below. The Danish king sees the young Grendel, but spares him. Later, Grendel finds his father's body and cuts the head off to take it home. Many years later, the severed (and mummified) head is inside a cave, apparently the centerpiece of a primitive memorial. The boy Grendel has now become as large and powerful as his father, and contemplating the head, he plans revenge.
