In the evening, they find a puppy, who immediately runs into the street, going in search of him, John and Sarah is attacking a huge dog that infects Sarah rabies. A flock of dogs surrounds the house, so friends quickly decide to leave the island, using the plane, but it turned out that the dog got already there, so the guys left to go back to the house. But soon the house is no longer a secure fortress, because dogs have found a way to get inside. Wild dogs could be nice to settle on the island, it was found that they were artificially bred animals with insatiable hunger, and almost supernatural intelligence, and their bites are irreversible changes in the human body.
