A Retrovirus, which was conceived as a tool for industrial genetic engineering, has gotten out of control and is spreading rapidly.

However, a small fraction of the earth?s population remains immune to the virus and must survive in this new and constantly changing ecological system. Tom cellar is one the survivors and on an old military base in the Eifel he has entrenched himself. Further survivors come together and succeed in carving out a life in this new world.
