Two mysterious events shock the world: In the middle of Tanzania, a kilometre-high barrier rapidly spreads across the land, swallowing everything that comes in its way. At the same time, a new, heavily overgrown continent emerges in the Pacific. Christopher, a teacher, experienced the formation of the wall at first hand. While he now flees from the black thing, together with his ex-girlfriend Max and the orphan Mtoto, the US officer Catherine Strive frantically works at investigating this new world, ever more convinced that this new continent alone will be able to offer a small circle of people protection. Massive political upheaval puts her determination to the test – until she realises that she can only save mankind by jeopardising her own humaneness.
