Loch Ness holds secrets, ancient and deadly. Does a monster inhabit its depths, or is it just myth? Why, after thousands of reported sightings and dozens of expeditions, is there still no hard evidence? Marine biologist Zachary Wallace knows, but the shock of his near-drowning as a child on Loch Ness have buried all memories of the incident. Now, a near-death experience suffered while on expedition in the Sargasso Sea has caused these long-forgotten memories to resurface.

On a desolate beach in far northern Scotland, the winter storms have been washing up all manner of things since time began. But buried in the centre of one smaller iceberg is a shard of ancient Viking pottery telling a partial tale of a hidden mysterious island beyond the ice and mist, that was home to a great treasure and even greater horrors. Thawing in the same block of ice was a rotting flap of skin that refused to be identified but had similar skin patterns to a creature not seen for 100 million years.

A bizarre series of incidents take place on a usually tranquil lake. Boats are found ravaged, a body torn in two, other people are missing and an injured victim cries of a monster. Chief of Police Morgan Sydney must face the reality that a huge monster is lurking in the lake. With bulletproof scales, territorial aggression, and an insatiable appetite, the beast causes mayhem in the peaceful town.

Dr. Hugh Meyer believed he had created the ultimate miracle. Using the DNA of ancient creatures preserved in the Arctic, he had genetically engineered one of the most remarkable species of sea creature to ever exist: the Serpent Eel. Believed to possess the cure for countless diseases, the creature holds great promise for the medical community. All goes awry when the beast escapes containment. With a rapid growth rate and remarkable physical evolution, the beast travels to the coastal town of Spiral Bay. There, the creature designed to save human life instead starts taking it.
