In 3×01 "No Place Like Home", 10 years have passed since the animal infection incident, and most animals have been cured. No more black bears break into the kitchens of ordinary houses, no more rats ravage elevators, and the streets of Washington, DC no longer look like African safari parks. Everything seems to be getting better, but humans have paid a high price - the drugs used to cure animals spread through the air around the world, and humans gradually lost their fertility. A new threat called "hybrids" began to emerge. They are an army of monsters created in the laboratory, and no one can stop their determination to destroy humanity. Gracie Dzienny plays Clementine, the daughter of Mitch Morgan and an adult this season. Clementine insists that her father is still alive and asks his former comrades to help rescue him. To cure human infertility, only Mitch can do it.
