A terrifying force unleashed on the Irish countryside.
Under a ruined monastery near the quaint village of Clareconnell, a labyrinth of caves hides a dark secret.
The remains of Grendel.
Defeated by Beowulf and entombed there by the Danes, he has remained hidden for a thousand years, guarded first by warriors, then by monks, and finally by the villagers themselves.
But nothing stays lost forever.
A team of archaeologists are excavating the monastery and searching for his grave.
