Nolan and Irisa arrive in Defiance, where the town is soon divided over the death of Luke McCawley. But a bigger threat forces everyone together: An attack by the Volge.

While investigating vicious Hellbug attacks, Nolan & Irisa realize they are tied to Irathient spirit raiders that have come into town. Meanwhile, Irisa starts experiencing strange visions.

Amanda’s mayoral campaign is threatened when Nolan is involved in an accident on the eve of the election, prompting the town to question Amanda’s decision to appoint him as Lawkeeper.

Irisa returns to Defiance and is arrested; Mayor Pottinger offers Nolan her release in exchange for capturing those responsible for nearly killing him; Stahma plots to keep Datak behind bars.
