The acclaimed Channel 4 series returns for its second season tonight and the stakes are high for the Synths as Niska goes on the run in Berlin and the rest lay low at home in the UK.

The Matrix's Carrie-Anne Moss joins the series as the show continues to go deeper down the rabbit hole of artificial intelligence gaining consciousness and things are only going to get darker the deeper we go. With new characters, Synth and human alike, it's anyone's guess about what could happen.
