When nearly every person on the planet becomes frozen a small group of survivors must navigate the darkest sides of human behaviour while learning about the creation of the world's first fully self-aware Artificial Intelligence.

In London, Yelena is trapped in a room after being sex-trafficked from Romania, and Alfie has one more drop to make then he's free of drug dealing forever.

In New York, Detective Joe Stephens is working a case. Life has worn him down. He's ready to end it. Poppy is a film-maker desperate to never go back to the UK, and Tripal is a clerk in a 7-Eleven that has a secret.

A secret that might be connected to why every human being on the planet just froze.
