Looking at themes not unlike sci fi hit series Westworld, Humans also examines the ramifications of artificial intelligence and robotics. In a reimagined present day, anthropomorphic robots called ‘synths’ mix in with humans and help them run their households. Starring The IT Crowd’s Katherine Parkinson, The Matrix’s Carrie-Ann Moss, and The Fall actor Colin Morgan, we’re now into series 2 of the show. In this episode, Athena challenges Milo over his ethics and is shocked to learn his plan. Max starts a new community of synths and learns how far Leo will go to achieve his aims. Meanwhile, Mia's return has ramifications for the Hawkins family.
