An officer of Maine Fish and Game researching American beaver populations is scuba diving in Black Lake, Aroostook County, Maine, when he is savagely attacked and bitten in half by something unseen in the water. A tooth is found in the diver’s remains and, as it appears to be a prehistoric fossil, a request is made for assistance to the Natural History Museum in New York City. Paleontologist Kelly Scott (Bridget Fonda) gets the job, mainly because her boss, with whom she has had an office affair, wants her out of his way so that he can pursue another relationship with one of Kelly’s co-workers.
Upon arriving in Maine, Kelly informs Fish and Game officer Jack Wells (Bill Pullman) and Sheriff Hank Keough (Brendan Gleeson), who himself witnessed the fatal attack, that the tooth appears to be reptilian in nature, and is not a fossil, but something much more recent. They also meet Delores Bickerman (Betty White), one of few people living on the lake, who claims to have killed her husband.
Later that afternoon, a helicopter arrives at the camp where we are introduced to Hector Cyr (Oliver Platt), an eccentric mythology professor, flamboyant multi-millionaire and crocodile enthusiast who believes, despite Hank’s intense skepticism, that the creature doing the attacks is indeed a crocodile. While the four are out exploring the lake, the creature is shown settling under Kelly and Hank’s canoe. Hector’s radar begins to pulsate as Kelly and Hank are thrown off their canoe and into the water.
The last scene shows Mrs. Bickerman feeding bread crumbs to what appears to be many baby crocodiles implying the two adults were a mating pair. During the end credits the surviving adult crocodile is seen tied to the back of a flat-bed truck speeding down a road.
