Because of biological warfare thousands of years ago, Earth was nearly destroyed and its current inhabitants are struggling to survive. Unbeknown to them, they are being aided by outside forces whose aim is to repair the damage done to the planet and restore it to a viable state.

One such restorer, bearing the title of Sower, is among those tasked with performing a necessary function that will rebuild the diminished population. This is done by - well, let's just say that he gets the job done. He is young, smart, resilient, and finds the existing main food staples of rats and cockroaches to be quite tasty.

In this, the final stage of the restoration plan, events get dangerous. The Sower has to hold his own with primitive males trying to kill him, and survive a night with eight native women.

Last, but not least, he finds himself racing to save his trapped AI partner from a new menace that also threatens the forests and places the restoration of Earth in jeopardy.
