On the first anniversary of a mysterious slaying, the masked killer responsible strikes again, butchering one of the earlier crime's eyewitnesses.

Connections to Kit are revealed in flashbacks, while a couple's secret affair is exposed via social media and another slaying strikes the community.

As school is dismissed for the summer, more shocking memories from the past year surface and a teacher who tries to be an ally to Saadia pays a price.

The Druid kills again as Amy recalls her role in Kit's death, Roberta questions multiple witnesses, and plans get underway for the solstice party.

Roberta and Pujit identify a suspect while Violet's lurid, exploitative murder blog goes too far, making her and Joe targets of outrage and revenge.

Attendees of the solstice party are stalked by the Druid while someone engineers a violent confrontation in the basement between Angel and Dan.

With the identity of the Druid revealed, the few remaining survivors inside the apartment building must make a last-ditch fight for their lives.
