News of the 'Killer Synth' finds its way into the media, causing widespread panic, and placing Karen under even more pressure to track down the alluring fugitive Niska. However, it seems there may be an ulterior motive to her hunt for the cuddleous synth. Meanwhile, the Hawkins debate whether to keep Anita in light of their recent discovery that she is not quite as 'new' as she seemed, and while Joe worries his domestic synth might inadvertently reveal his secret, Mattie's decision to place her trust in Leo could put an end to the family's arguments.
Humans is set in a parallel present where the latest must-have gadget for any busy family is a 'Synth' - a highly-developed robotic servant eerily similar to its live counterpart. In the hope of transforming the way they live, one strained suburban family purchases a refurbished synth only to discover that sharing life with a machine has far-reaching and chilling consequences.
