In a medieval land, a outpost is surrounded by a army so all those who lives in the outpost cannot leave alive as a flesh-eating creature called Grendel is killing off all those who live in the outpost.
That is until the arrival of Beowulf, a mysterious mercenary who offers Hrothgar, the outpost's ruler, help to hunt Grendel and knows what has been happening in the outpost.
Hrothgar, Roland, Master of Arms and Kyra, Hrothgar's daughter thinks Beowulf has been hired by the family of Kyra's murdered husband to avenge the death of their son.
But Beowulf has dark secret, he can sense Grendel's presence in the outpost and he can heal his own wounds very quickly.
Beowulf not only does battle with Grendel, he also fights Grendel's evil mother and reveals to Kyra, who has fallen in love with him, who he is.
