B Smith and the other Angels are relieved to finally receive their first mission – to safely escort a group of human survivors from the zombie-infested streets of London to New Kirkham, a barricaded safe haven in the country. But after battling through crowds of undead monsters, B discovers that the survivors of the town don’t necessarily represent the best of humanity. And when evil influences make their way to New Kirkham, unearthing demons from B’s past, the humans will be forced to choose between being honorable and being safe.
