Humans

A year after all the synths gained consciousness, wary humans have created docile, orange-eyed synths, while Mia and Max lead a settlement for green-eyed synths.

Niska and Mia attempt to rescue a group of synths who were stranded while trying to cross the border, and Laura is assigned an orange-eyed synth for her protection.

Mattie brings Leo to the Hawkinses’ house, but Laura is distracted preparing for dinner with her colleague, Dr. Neil Sommer. Mia faces discrimination trying to live among humans, while Max struggles to lead the synth settlement, now rife with anti-human sentiments stirred by Agnes.

Laura brings the members of the commission to visit the synth settlement, hoping to inspire understanding between the two groups, but Max worries about what Agnes might do. Mia receives a surprise visitor, and Niska follows a new lead in her search for the perpetrator of the bombing.

Laura helps pass legislation to prevent human attacks on synths, but the victory is short-lived when Joe brings home Sam, the synthetic child. Because of the new protections, Max decides to open the gates to the settlement, and Mia finds more supporters.

Both Max and Laura remain optimistic about Mia attending the commission, unaware of the betrayal within their own households. After receiving some surprising news, Matty helps Leo search for the source of his memories, while Niska gets closer to finding the enigmatic “synth who sleeps.”

As Sam arrives at the synth settlement, Max reveals who betrayed them, and the members of the settlement are forced to choose sides. With Mia in custody, Laura suffers a crisis of conscience, and Niska continues her investigation with a new ally.

Niska is shocked when she finally learns the identity of the “synth who sleeps.” Max takes back control of the synth settlement, while Laura races to prevent the implementation of Operation Basswood, a government plan to destroy all green-eyed synths.
