Welcome to Black Lake. Its placid waters compliment the pristine Maine wilderness it borders. This tranquil setting is probably the last place you'd expect a gruesome fatality. But then it's also the last place you'd expect to find a 30-foot, narrow-snouted, multi-toothed, reptile of the species Crocodylus--an eating machine more commonly known as a crocodile. It is at this lake where an emotionally fragile, nature-phobic, New York paleontologist who's been reluctantly dispatched for her first real field assignment, teams up with an eccentric billionaire to find this menace.
