Hatched in a toxic landfill and raised on a diet of composted vegetation and waste paper, Gideon grows into a well-read, well-fed fly with an idealistic worldview.
Through his acquaintances with the other landfill residents, Gideon meets Pincer, an enigmatic cockroach with a cult-like hold over the inhabitants of the dump. Pincer knows of the dream home Gideon seeks, having spent time in the manor belonging to the corrupt proprietor of the landfill.
Despite warnings from the cockroach, Gideon is determined to cut his ties and make the manor his new home.
But Gideon soon finds that the manor holds its own cruelties, dangers and dark secrets.
When he uncovers plans that threaten the whole way of life for his old compatriots, Gideon knows he must act before the landfill descends into a dystopian wasteland.
