Johanne is a marine biologist who is doing research on a fish farm in Vangsnes, a rural community located by the fjord, when she encounters several strange occurrences. Along with the brutal deaths of two local teenagers, all signs are pointing to the deep fjord; can there be more to the depths than the eye can see? At the bottom of Norway's deepest fjord rests a mythical monster as large as a mountain, with a myriad of arms ready to crush and devour anything they can grab.
