In Season 2 of “HUMANS,” Niska (Emily Berrington) releases the consciousness code, but it doesn’t work as she expected; newly conscious Hester (Sonya Cassidy) causes concern for Max (Ivanno Jeremiah) as her violent tendencies start to turn Leo’s (Colin Morgan) head, and Mattie (Lucy Careless) salvages Odi (Will Tudor) to test a theory.
Meanwhile, Mia (Gemma Chan) forms a relationship with a human against her family’s advice; Pete (Neil Maskell) tries to find a way for Karen (Ruth Bradley) and he to be a true family; and as Synths begin to disappear, Leo becomes obsessed with saving them.
Elsewhere, scientist Athena (Carrie-Anne Moss) pushes her research to the limits, but when she suspects her sponsor Milo (Marshall Allman) of having darker reasons for funding her dream, she must make a tough decision; and Laura (Katherine Parkinson) agrees to take on an impossible case.
One year after the dawn of consciousness, a decimated and oppressed Synth population fights to survive in a world that hates and fears them.
In a divided Britain, Synths and humans struggle to broker an uneasy peace, but when fractures within the Synth community start to appear, all hope of stability is threatened.
Set against the maelstrom of political chaos, the ethical complexities of the dawn of a new species play out across a thrilling, multi-stranded narrative.
As the Synth family, Mia (Chan), Niska (Berrington) and Max (Jeremiah) continue to battle for their right to survival, Joe (Goodman-Hill) Laura (Parkinson) and their children Mattie (Lucy Carless), Toby (Theo Stevenson) and Sophie (Pixie Davies) struggle to come to terms with the cataclysmic events of last season.
