A vicious genius created a creature unmatched in nature for its ruthlessness and power. Enjoying its might, driven by a single instinct—to kill—it destroys all living things around it. In a short time, several residents of a small American seaside town are literally torn apart. At first, suspicion falls on a giant white shark appearing in local waters. But scientists object: these predators don’t kill with such brutality, and later, in the bodies of the victims, steel teeth are found. It has also been observed that at the sight of humans, ordinary sharks become excessively aggressive, and peaceful marine creatures have begun to fear people. So what new monster is terrorizing the town’s beaches?
