After

Luke and Alex have only days to stop the plague…

But for the rest of the crew, it's already here. The fog filled London’s streets and everywhere it went, people started dying. Now those the flower seller saved from themselves have a far larger, far hungrier foe.

Can Bayleigh and Layla survive the horror that has beset them? Will Jackson prove himself worthy of God's love? Will Krystal and Ed make it across town alive? Will Dave ever stop running?

As Luke and Alex make one last ditch attempt to stop the plague, they meet someone who changes Alex’s life forever, and makes Luke question everything he thought he knew.
