Steve and the team are on the search for deadly animals in the steaming swamps of the southern USA. The contenders are everywhere, not least the alligators that live in just about every pond and lake. But the first animal on the list is a complete surprise, a monster fish with two rows of sharp fangs that certainly keeps Steve on his toes. The crew find themselves up to their armpits in a swamp hoping to find a deadly snake with the unusual name of cottonmouth. Last but not least, Steve and his team come face to face with an enormous record-breaking predatory turtle.
