Laura meets a client who thinks synths can feel emotions and deserve human rights; she is intrigued by the idea. Meanwhile, her husband Joe feels lonely while she is away and has sex with Anita.
Mattie meets up with Leo in a café; when Leo claims her synth is called 'Mia' and wants to meet her. She claims to need the toilet and runs away. Max then tells Leo that he has found something in Anita's code: they discover David Elster had left executable code within Mia's programming. They find Doctor Millican, who helps them extract it. Leo connects himself with his laptop and tries to run the program.
Niska finds a "Smash club" where synths are savagely beaten for entertainment and starts attacking the humans there with a baseball bat; she is cornered by police. Leo rings her and says she needs to meet him, because he needs her code. Niska grabs one of the officers and threatens to kill him; the police let her escape.
Laura and Joe take Anita in to be diagnosed and discover she is at least fourteen years old and may have been illegally modified. Meanwhile, Pete Drummond's wife asks him to leave their house for a few days, growing sick of him and increasingly fond of their synth, Simon; Drummond goes to stay with his colleague Karen. Unbeknownst to him, Karen is a synth herself.
