Crover Island

The most visible threat to humanity isn't always the most dangerous.

Crover Island, a small land mass just past Inverness, is inhabited by toughened Scots who have lived and fished there for generations.

University student Tim Kempson arrives on the island just ahead of Hurricane Nora, green under the gills from his rocky boat ride, but not too seasick to instantly fall for Marie, the strong-willed daughter of the local pub owner.

As a trio of fishermen launch a business to capitalize on the legend of the Loch Ness Monster, and Tim and Marie explore their new relationship, the island is hit by gale force winds and torrential rain. Then a shockwave jolts the northern half of the Great Glen Fault, causing the entire island to shiver.

What's written off as an insignificant tremor by those above sea level releases an army of horrific underwater creatures far more real than Nessie will ever be.

And they're hungry.
