Trapped in a suffocating depression inside his East Village tenement, confidential informant Rufus O'Callaghan struggles to find a reason to keep going. Haunted by sleepless nights, a fractured past, and painful isolation, he finds himself entirely adrift three months after a devastating loss. But as the relentless noise of the city closes in, a dangerous new chapter is about to begin.
