Shark

There's something in the water...but this time, it's not what you think it is. At a small marine institute off the coast of Connecticut, a young marine biologist, Simon Chase, studies and tracks sharks, whales, sea lions, and a vast array of other threats to the ocean's environment. With his young son, he begins to notice strange behavior among the creatures of the sea; something in the ocean is throwing off the balance of nature. Then the body of a diver washes ashore. When more victims are discovered, Chase realizes that while the killer resembles a white shark, it is far more dangerous and malevolent than any shark he has encountered before.
