During the reign of the Vikings, Kainan, a man from a far-off world, crash lands on Earth, bringing with him an alien predator known as the Moorwen. Though both man and monster are seeking revenge for violence committed against them, Kainan leads the alliance to kill the Moorwen by fusing his advanced technology with the Viking's Iron Age weaponry.

Freya: If you truly believe that you write the tale of your life, then the end is up to you.
Wulfric: This is where your ship went down?
Kainan: That's right.
Wulfric: In a lake?
Kainan: Don't ask.
Kainan: This thing has carved out a territory and you're in it!
Wulfric: We could have been friends.
Kainan: We *are* friends.
