Bunker is set into a post-apocalyptic future, where not much has left of the world as we know it. Territories are controlled by clans, the world is wrapped into clouds of ash and toxic gases, rivers are polluted, cities destroyed. In the evenings the bar turns into one of the most popular, as well as one of the most guarded hangout spots in district X (former Murska Sobota, Slovenia), where the survivors clans of the apocalypse from near and far are gathering.
