In 2050s London, fear grips like a vice as a deadly virus sweeps the globe. The British prime minister tells her people to remain calm. A vaccine will be available soon, and as a precautionary measure children will be whisked away to undisclosed locations, kept safe until the storm passes. Marianne, Downing Street press secretary, doesn't realise the futility until it is far, far too late. When the truth hits her, Marianne is forced to choose: stay with her family, or do whatever she can to help the doomed survive. As London falls, seven-year-old Maia is one of the last to escape the city. In an evacuation camp, she binds herself to Finn - in the absence of everything she knew, he becomes her everything. Yet as the years roll on and hope fades, Maia sees the bubble of safety is also a prison. She realises there is only one choice - to leave the camp and find what remains on the outside.
