After being reunited at Annie's memorial, Kieran and Harlow begin separate searches for their lost friend, all while trying to repair their friendship. Harlow, recently retired from the CGI company she helped found, discovers fragments of the dead - faces, gestures, glances - in AI generated videos; meanwhile Kieran, aimless and isolated, stumbles into an occult community of those dedicated to finding the missing ghosts. The friends' journeys will lead them through a world at once recognisable and strangely removed. A subterranean world of endless tunnels filled with ominous arrangements of consumer goods; a world of seances where attendees are haunted by the empty spaces where ghosts used to be. As Harlow and Kieran are drawn deeper into the circumstances behind Annie's - and the ghosts' - disappearance, a terrifying, singular pattern breaks the surface.
