Robin lives with her sister Laney in the idyllic orchard town of Montague. While at work at the fruit packing house, she finds a insect that she believes to be invasive. When her boss Dennis brushes away her concerns, Robin goes public with her finding. The reaction is swift: the factory shuts down, the farms are placed under quarantine, and the majority of the people in Montague find themselves unemployed with Robin to blame. Meanwhile, Robin has been struggling to get an abortion. Unable to take control of her own body, she devotes herself entirely to finding proof that the bug she found was real. The parallel between these two invasions becomes clear as she loses herself in her obsession.
