The Safe Haven refugees hoped that they would find respite in Glasgow. But a devastating chain reaction is in motion, threatening not just their plans but their very existence.

Chaos flows through the streets like a fast-moving river. The infected run rampant, and to survive, Mike and the others will have to fight like they never have before. This is the battle of their lives and survival is everything.

Horror and devastation reign. Today, the city has become a war zone. Tomorrow, it could be their graveyard.
