When Madita buys a children's booklet with a kit for breeding trilobites in a supermarket, they have no idea that they are unleashing a devastating threat. After the crabs hatch from the eggs, they notice that something is wrong with the animals - they are larger, more aggressive and able to survive in the air. Soon the crabs spread throughout the city, killing and eating people. It turns out that the crabs come from a secret research laboratory and were bred to combat overpopulation.
