Vic searches for Arisa, who is hidden in the Safronov household by Sonya; Det. Varlamov investigates a murder linked to anti-bot vigilantes.

Safronov plans to return the lost bot until Arisa saves Sonya's life; Vic's powerful father-in-law, Losev, negotiates a deal that hinges on Arisa's return.

Varlamov closes in on both of the Safronov men but has a better case against Egor for the Liquidator protest; Arisa attempts to protect her "family."

Egor is pulled deeper into the Liquidator as their secret backer is revealed; Safronov -- his career restored by Vic -- learns of his patron's crimes.
