Lake Enforcement Officer, Bruce Wright has a problem, and it isn't just a busy vacation season full of festivals, summer camps, fishing tournaments, boaters and beachgoers. If only that were all he had to worry about... Unfortunately, there is something lurking in the depths of picturesque Lake Riley; something that should not exist, something insanely large, voracious, and bloodthirsty, and it is on a killing spree that will not end unless Bruce can find a way to stop it.
