Following a series of green-eyed synths malfunctions and human deaths a new, orange-eyed, breed is created with the likes of Mia and Max in an internment camp and in need of spare parts. The Hawkins family is shocked to learn that a bar welcoming both synths and humans is fire-bombed with Niska's girlfriend Astrid among the casualties. The news that the perpetrators were synths leads to reprisals against the green-eyed population and Joe walking out on the family when the female members champion the synths. Mattie visits the camp, where Leo lies in a coma, but it is attacked by armed police looking for the bombers. Meanwhile Karen Voss sends little Sam to school.
