A huge mutated crocodile suddenly appeared in a beautiful town. It was violent and ate everyone it saw, and the entire town fell into terror. Sheriff David began an investigation, and with the assistance of his wife Chris, who worked in the laboratory, they found that the wound was caused by an alligator. After entering the sewer, they found a highly toxic chemical that had been dumped by people. They inferred that it might be a mutant crocodile, and the monster was still breeding in large numbers. The police team that originally wanted to hunt giant crocodiles turned into prey. The team members were brutally dismembered, and one after another they were swallowed bloody! On the other hand, at the same time, Winnie, the town's pharmaceutical magnate, was trying to get the townspeople to sell their houses, thus obstructing the case in every way. Villagers became targets for silence and were chased along the way, falling into a situation of being attacked by humans and crocodiles. At this point, a thrilling battle between humans and crocodiles began!
