The Hawkins family buys a Synth named Anita. But are they in danger from her? And why is the hunted young man Leo desperate to find her? Meanwhile, George's beloved Synth, Odi, malfunctions, and Pete is jealous of his wife's Synth.

Niska stages a brutal escape from the brothel, and Leo's secret is revealed. George is horrified to be given a new Synth, Vera.

Anita saves Toby's life--but is there something strange about her? George breaks away from Vera, and Pete stews over the brothel murder cover-up. Niska enjoys her freedom--but has she found a second victim?

Joe gets too close to the beautiful Anita, whilst Karen is perhaps not what she seems. Leo gets one step closer to finding Mia and Niska wreaks revenge.

With Karen hot on her trail, Leo sends Niska to George's house and an unlikely friendship begins. Joe's secret threatens to destroy the Hawkins family.

Laura tells Mattie her secret, but Pete rejects Karen when she confesses the truth. Leo and Mia are reunited, and Max makes the ultimate sacrifice.

A desperate Karen continues her pursuit of Niska. The Synths stay with the Hawkinses, but Hobb is not far behind.

The Hawkinses help the Synths escape, and they are finally a family again. But what is the future for Synths and humans?
